It is also said that there will soon be an announcement for a new Pentax DSLR or even EVIL(ILDC) on February 8th, which from my best sensible guess, should be the K-5 Silver but not anything else, if the rumour is to be true.
After all, remember these are rumours. And they are very wild ones.
Update: K-2 should not exist, K-2 is simply K-r in Mandarin!
