Just hope that contrast AF works during movie mode, it manages to reduce CMOS wobble and it has full manual control of aperture, shutter speed and ISO for movie mode.

Is it even 100% the camera has contrast AF?

I think it is almost certain now. With a dedicated LV button (and not hidden and needs to be enabled in the menu), and the talk about ?77 AF zones...

That doesn't make sense.
Well I think it won't be 1080p, but it will be 1080i

1080p and 1080i are two different 'format's.
The 1080i is the standard video signal for HD televisions, the 'i' stands for interlaced.
The 1080p is the highest quality for HD televisions, the 'p' stands for 'progressive scan'.

So 1080i is the 'lighter' variant so it should be easier to implement ?

I am really hoping this camera is not a big letdown after all the hype surrounding it. Anything less than a D300 beater with video is going to upset a lot of people ... and the daft thing is Pentax have not released a single spec yet.

Fingers crossed.

Who the hell gives two shi*s about video??????? This is a camera, not a video camera. Not to mention a "pro" DSLR. I could careless. As a pro I want something that taks great photos not videos.
This makes sense if you think video as "soccer mom with cheap camcoder" blurry, shaky, awful, boring. But video with SLR lenses is more on the Hollywood side of things, it will expand our artistic possibilities.

Sensor cleaning, that's a gimmick

Actually, the frame rate should also be looked together!

1080i at 50Hz is no difference from 1080p at 25Hz - they just scan the lines in different orders!

A 1080i/50Hz video signal still gives you 25 complete frames per second in 1080 scan lines. For 1080i/60Hz, it has 30 fps.

So, if we have 1080p at 24 fps or even 20 fps for a video-capable DSLR, it is just very slightly worse than a traditional 1080i video picture displayed at 50Hz, say, through a component video signal cables and a display panel.

Actually 1024p exists, i think it's only an aspect ratio thing.

1024p/i is a 4:3 format whilst 1080p/i is a 16:9, which is the current popular video standard, even for HDTV broadcasting.

Again, the aspect ratio has nothing to do with the refresh rate of the *whole frame*, which can only be known and compared by *both* the scanning mode (progressive or interlacing) *and* the scanning rate in Hz.

K-7 is Pentax's mixed version of D2X/D200/E3 with video, with strongest weather resist, smallest and lightest semi-pro APS-C.

Well, It kind of is.
Its very rugged like the D3X
High Res.
Video.
Around the same framerate.
Big viewfinder
But all in a smaller package and with cheaper lenses.
