Pentax 645Z vs 645D – What are the main differences?

Pentax 645Z

I made a quick comparison of the recently announced Pentax 645Z to the 645D. Here are  the main differences:

Pentax 645Z vs 645D:

– Higher resolution sensor: 51.4 MP vs 40 MP

– CMOS sensor vs CCD sensor

– Video recording vs No Video recording

– 3.2″ LCD screen vs 3.0″ LCD screen

– 27 focus points vs. 11 focus points

– 3 fps Continuous shooting vs 1 fps Continuous shooting

I see 645Z as a significant upgrade over 645D, mainly due to higher resolution sensor and video recording capability. Also I always thought that 1 fps of 645D was a bit limiting at times, so 3fps of 645Z is a welcomed addition.
