Pentax Ricoh need to do three things as regards the K3 Two of which are actually relevant to the conversation here!
1:
Make sure that the supposedly coming 100ish to 300 and a lot-ish, and the 70-200, and indeed any lens after that has a motor in it and is able to focus quickly, IE, shorten the focus throw by a big margin and get a quick and reliable mechanism to back it up, whether they use the SDM system or the one in the 18-135 et-al does not matter as long as it works quickly efficiently and quietly.
2:
They need to cuddle up to Sony (Probably Patented) and get hold of the tech for the in body focus limiter from the Sony A99, I hate the idea of anyone "Cuddling up" to Sony but needs must, it would give some of the older SDM lenses a chance when it comes to AF, the throw is so long on these that when they either lose focus or fail to acquire they are sooo far out they just give up! Being able to limit the travel relevant to your subject matter would be a big help.
And 3, unrelated to the current topic but one for me:
They need to ask Hassleblad nicely if they can implement the super resolution tech via sensor shift, that their new MF cameras have, 90 odd mega pickles would be s huge talking point and get the average joe interested, big numbers are after all big numbers and create interest in the brand as a whole it's a headline grabber and must be possible given the control that is required for the selectable AA filter?

@Richandfleur
I get where you are coming from on the mirror-less aspect with a caveat, the CDAF on these is still poor if the subject moves, flooding the screen with sensors is no bad thing though it does give you options, I have not tried any Olympus's but have experience with the Fuji X-T1 and the Sony A7 series, the Sony A7/r are worse than any Pentax in the focusing department but the Fuji is as good as your K30 using it's nine centre PDAF points on board the sensor. The exception to all of this is the Nikon 1 series which is just incredible! Other than the Nikon 1 series, they don't quite match the K5II/s and are a mile behind the K3, it's the lenses that let down the K3 for sure...

Not wanting to derail the thread but does it come with some of your expertise built in?
What a lovely set of images on your site sir, top class, I can only aspire to that, beautiful...

Robs a nice bloke, somebody buy his Macro!

Both now secured!

Mate of mine is a dyed in the wool Nikon shooter, with a full raft of APSC bodies and glass as I used to be. He used to manage the Sunderland branch of Jessops and latterly co managed the big one in the Metro, until the S.H.T.F. a bit back, he picked up a K30 kit with the two WR lenses, when he left, just for kicks, the end result? The Pro Nion Kit with all it's glass stays at home. Apart from the AF which pails compared to his D300s, and the fact he had to get used to the differing metering priorities it has, he loves it! It goes everywhere with him...
Strike one for the K30!

Looks a lot better like this though? Well maybe not the colour although I quite like it...

My take is a little different to most.
Having had most of everything I have found that Pentax's K series is the Camera I end up hating the least! The K3 is head and shoulders the best of em.
The only caveat to the whole system is the lenses, some of em just ain't.up to it in regards to the K3 sensor and AF. Give K3 the glass and lenses with quicker AF, it will get you the shot!
Listening Ricoh? No I didn't think so...

Jules is currently in negotiations for one for £425, Yours looks lovely Rob but I just don't have £500, sorry...

Take your K-S1 out in one of these bags Algi!
A7R won't go in, it's Pentax only!

Lifted from Dpreview but I thought it was an interesting take...

IF IT WAS A NIKON...

"DPR's Hands on Preview might have been worded somewhat differently :

PENTAX: In most situations, they serve absolutely no purpose. If you're using the self-timer, the lights will 'countdown' the seconds until the photo is taken.

NIKON: While in most situation the LEDs remain simply decorative, when using the self-timer, the lights will 'countdown' the seconds until the photo is taken instead of the traditional flashing red light.

_________

PENTAX: Despite Ricoh's love of cameras that come in numerous colors, there's no way to adjust the color of the LEDs.

NIKON: The LED colors remains constant; however, Nikon will at last, be offering this camera in a number of attractive colorful combinations.

_________

PENTAX: We bashed our heads against the wall for a while trying to figure out how to adjust the ISO/flash/drive/white balance settings on the four-way controller, but it only takes a press of the 'blue button' to switch functions.

NIKON: Though perhaps not the most intuitive (but clearly shown in the manual), it only takes a press of the 'blue button' to switch the functions of the four-way controller, hence avoiding having to rely on often awkward menu selection.

_________

PENTAX: Pentax has given the menus a new font. And it's about time.

NIKON: Nikon has given the menus a new font, which greatly enhance readability.

_________

PENTAX: the grip is a bit small (it's slippery as well).

NIKON: the grip is not overly bulky, though some might find it slightly more slippery at times.

_________

PENTAX: The mode dial is very stiff and difficult to turn. One DPReview staffer thought that he was 'losing skin cells' trying to turn it.

NIKON: The mode dial is firm, and will not switch mode accidentally. One DPReview staffer thought that it definitely needed a bit of pressure to turn it.

_________

PENTAX: One of the best features on Pentax's DSLR is a large viewfinder. The one here has a magnification of 0.95X and 100% coverage.

NIKON: A first amongst Nikon entry to mid level DSLRs, the D-1S features a large, bright, optical prism viewfinder, with a magnification of .95X and 100% coverage.

_________

PENTAX: There's nothing terribly exciting on the top of the K-S1.

NIKON: Top provides a clean, non-intimidating feel to first time DSLR users.

_________

PENTAX: Aside from the pulsating lights on the front of the camera, one of the most confounding questions about the K-S1 is why it's priced higher than the K-50, which is superior is nearly all respects. With their 18-55mm kit lenses, the list price of the K-S1 is $799, while the K-50 is $779 (and that's with a water-resistant lens).

NIKON: Aside cosmetic and ergonomic changes, the D-1S inherits some of the more advance features of its recently released pro-level sibling (e.g. moiré reduction), features a new 20MPix sensor, while remaining essentially very similarly priced as its predecessor.

_________

PENTAX: While the somewhat bizarre LEDs on the K-S1's front grip will likely garner the most attention, under the hood it seems like a quite capable DSLR.

NIKON: While the innovative LEDs on the K-S1's front grip will likely garner the most attention, under the hood it is still quite a capable DSLR.

_________

PENTAX: The specs of the camera are more impressive than the ergonomics. We like the large optical viewfinder and backlit mode dial, though the latter is rough on your thumb. The four-way controller is poorly designed, and the grip is small and slippery. The LED lights on the grip are more style than substance, but at least you can turn them off.

NIKON: The specs of the camera are as equally as impressive as its ergonomics. We like the large optical viewfinder and the backlit mode dial. The four-way controller is cleverly designed, and the grip is not too bulky. The LED lights on the grip are stylish as well as functional, and you can turn them off when you wish to be more discrete.

_________

PENTAX: The biggest issue we have with the K-S1 is figuring out its target audience. Its design (including those LEDs) makes it stand out in the crowd, but the biggest selling points should be what's inside.

NIKON: It is clear the the D-1S is aimed at the younger X-Generation. Its design (including those LEDs) makes it stand out in the crowd, though what the inside provides should keep it attractive even the more serious photographers."
