The Pentax 645D will have 40 megapixels

UPDATE (March 9): The Pentax 645D and a new 55mm f2.8 645 lens have been officially announced. [NEW!]

Now back to the more serious topics - although at one point the 645D was a "$5 task" ;-) Pentax Japan has updated their 645D teaser (memo to Pentax-Japan: please create text-based teasers so we can computer-translate), and DC Watch Impress human-translates it. The new revelation is that the camera will have a 40-megapixel sensor, but they do not reveal the type of sensor (CCD? CMOS? other?) or maker (via Foto Actualidad)
