No 64GB is not in the SDHC standard.
SDXC is for 64gb and up and Thosiba announced they will have those this summer.
SDXC will probably also work with some SDHC devices if you reflash the system file format to FAT32 since the standard for SDXC is exFAT, one of the reasons is because exFAT doesn't have the 4gb file limit.
I ain't sure if the device need to support exFAT to get the SDXC label (support) on it?
If the answer is yes then we will probably never get an update to SDXC with the current camera's since it's a bit more complex then going from SD to SDHC.

Isn't there a problem with the image sensor and noise?
I thought that having the sensor only exposed for a brief time is better for its noise performance. That would imply you would need another sensor, working all the time to feed your viewfinder and, thus, you'd still need a swinging mirror or something to route the lighe between sensors. Possibly an electro optic shutter / reflector?
Yes because of the heat build up but the thing about the shutter is differend.Isn't there a problem with the image sensor and noise?

They still need to have a mechanical shutter because the computer isn't fast enough to read out the sensor and reset all the pixels in the time needed to get a good photo.

Yep, I could refund them but I've kept them and will buy some cheap second hand flash from ebay, it's cheaper then getting a sync that does work.... they all work.

The Cactus v4 do work with the Pentax AF360, the design of the syncs are good and the quality decent for the price.
There are some report of the Cactus not working but it fired my flash all the time, it never failed it just syncs to slow with the Pentax AF540, I can only use shutterspeeds slower then 1/15 of a sec
But like I said that isn't the case with the AF360 from what i've heard.

The remote trigger also works with the flash in "M" and "A" modes as well
Don't forget they are optically triggered, not by radio.
Please realise, however, that as your built-in flash can only operate in P-TTL mode, it will pre-flash and trigger your flash early - and it may not have enough power left for the exposure-making flash. If using your flash remotely in M or A, use an old cheap manual flash on your camera to trigger.The remote trigger also works with the flash in "M" and "A" modes as well

What you said is true with the older flashes that only has "dumb" slave mode the newer flashes have a smart slave mode and you can pick 4 channels.
You don't need to have your flash set to P-TTL but you can also set the flash to A or M and it won't fire with the Pre-flash because of the smarter sync.
Hiljon has a Pentax 360 and that one support the smarter flash mode.

K-M vs K200D is easy
The K200D has more to offer then the K-M, the K200D has 7 focus spots and the K-M only 3 and has a top LCD, focus point indicating in the viewfinder, weather sealing and you can get a grip for it.
The K-M is smaller and lighter, nothing more can be really said about it. The sensor and all the rest that's used are the same.
The K10D is another camera all together but that has been said already a lot of times.

Every is forgetting the AF system, most of you already are complain how slow it is, have you've tried the AF when using live view because that's the same you will get with an EVF.

Didn't had a problem yesterday when uploading the brown/silver K7 photo...

Calling Pocket Wizard and then asking them which other company sells the same things they do... yeah I don't think they would love to answer that.I would have thought that Pentax support was precisely that, support for Pentax products, maybe 'Pocket Wizard' support would have been more worthwhile.
It's like calling to Mercedes and ask them what other Germany company makes cars.

I remember some complains about the colours and that we don't need them so it's funny to see the white and red or doing better then black
And it seems that our discussions about some entry level primes are hinted and also the weathered sealed flashguns, let's hope they listen.
Since they mention they are still working with Samsung and being there are some reports of the backlit sensors just like the EXMOR R from Sony we might see that in the upcoming camera's.
