Pentax 645D II ?
Images (not verifiable) have now begun to appear on the internet of a new Pentax 645D II to be revealed at the CP+ Camera and Photo Imaging Show in Tokyo next week.
No news of the exact sensor, but a tilt screen would suggest live view, which would mean CMOS not CCD.
The Pentax K3 is arguably the best APS sensor DSLR on the market, and it looks like the new 645D will rewrite the rules for medium format digital. For Pentaxians we live in exciting times.

I’m waiting for the price tag…
Guess we have an answer now, the 645Z. $8500 seems like a great price for the professional photographer.
