From an interview video clip with a Pentax official at PMA by a Swedish online magazine:-
The following dialogues are recorded (at around 1:00 from the starting):-
"We have planned to introduce a new SLR, it's also a new concept, by the summer."Q: "Is it a direct successor to the K20D?
A: "No, it is not a direct successor of the K20D, the concept has changed during the development in the past months, the concept is slightly different."
Q: "Is it a more advanced or less advanced than the K20D?"
A: "It will be more advanced I would say."Although it is not a new thing for a new upper level Pentax DSLR (within their family) to come this Summer, which was disclosed last year at Photokina by a Japanese senior Pentax official, the above interview re-confirms the thing lately, at least. Btw, I think whether it is a "K20D Successor" is almost meaningless, as the K20D is virtually a dead model now, in terms of its sales volume: ridiculous low price but yet still low popularity. So, if a new Pentax model above the K-m is not to come sooner, Pentax will just have no market share on anything at all other than only a little bit share in the entry level DSLR segment. Hence, they should act faster. And indeed, much faster, as it should be.
