The Future and Who Should Upgrade
Pentax has informed us that future plans include the introduction of a high-end APS-C DSLR as well as a full-frame DSLR. At this point, it's not a question of whether or not these cameras will come, but rather when. For those who do not want to wait a year or more for these advanced cameras and are currently using the K-5, it makes sense to upgrade to the the K-5 IIs. Similarly, those using other Pentax cameras will greatly benefit from the upgrades in the K-5 compared to older bodies such as the K-x or K10D, but may prefer to go for the cheaper K-5 rather than the K-5 II.

Even his own shots show this ...... as you can see here

You can compare K-5IIs/K-5II/K-5 shots here under controlled conditions



However the AF on the K-5II/K-5IIs has been proven to be much better than the original K-5.

Personally I would recommend waiting a few weeks as we're getting close to the release of a new batch of Pentax models and you may find that the K-3 ( or whatever it's called ) will offer much more than just an interim improvement of the AF as the K-5II has done.
