The Pentax "rumourizer" OGL has made a post about an alleged interview with Pentax Ricoh Russia as cited from another Russia forum post:

So, the following are rumoured:
1. FF will be next year. Not later than Photokina 2014. Maybe, on spring or summer, 2014.
2. New DFA lenses will be offered. New 2.8 zooms will be made.
3. New Limited Zoom will be real.
4. New WR lenses will be launched.
5. K-01 is failed because of design. Mirrorless cameras - Ricoh will offer something new.
6. New 645D will be later. It will be different from 645D. It was plans to launch 645DII this year, but the situation is changed.
7. SMC DA LIMITED are discontinued.
If the first rumour is true, then there is just no reason to buy a K-3 now, which is really a true stop-gap product. So, I believe in that rumour and will keep using my K-5 and wait just for a few months longer! ;-p
