On second look at the 1080p file, the resolution seems noticeably improved over the 5D2. Not true 1080p, I agree, but considering the reduction in moire and aliasing, I think the resolution is pretty good. That's no excuse for Canon, but I'm not as turned off as I was earlier.
I do a lot of still photography along with video work (about 50/50 actually) so I am still paying close attention to the 5D3 and am likely to order one too...
