I would have been content with 720p. In fact, I *really* wanted the D90 to be my camera. Unfortunately, the rolling shutter is much worse on the D90 than the 5D2. But the real decider for me was the codec. My goal was to make some video beauty shots. The D90 codec doesn't really allow that.

The 5D2/7D encoder is what truly separates Canon DvSLR video from its competitors. The rolling shutter is better too, but still has lots of room for improvement.

The new Nikon, due for launch next month, will not be 720p but a full 1080p in full frame format (although there are hints of Nikon offering the video inside the crop mode, but I don't think so...well, certainly hope not!). I think it will offer 24fps in HD video mode, with up to 14fps in HS stills mode, although if it doesn't also offer the video 25p & 50 options like the 7d for all of us in Pal world I'll not be happy).

I'm due to return to France to complete a filming project (that was cut short last month due to flooded cameras!) and would like to take a new hybrid stills camera along with my present camcorder & stills cameras equipment. I have been tempted to take a 5d Mk2 or 7d along as well, but would rather take a full-frame Nikon camera like the D3s or D700s instead of a D300s or 7d. The only problem is that the due-launch dates are tight to my trip dates - so I'm crossing fingers to get my hands on one before leaving.
