The above screenshot was taken form Pentax Canada. The official release will be on May 20 (US & Canada) and May 21 in Japan (not sure about Europe yet). There is a whole web site dedicated to the new Pentax K. It is also not clear if the model name will be K or K-7, since all banner just say "The New K", but maybe they refer to the whole K series and not to the specific model K. Check out the chronology of Pentax K events.
