It is probably reliable resolution with some particular 1000x cards, for instance my 16Gb Transcend 1000x at 1728x972 gives me only around 500 frames.
Sure. There are plenty of threads about recommended cards. With the 32G Lexar cards I'm using in my 5D Mark II, 1728x972 has been about 95% reliable up to around 2 minutes and I haven't tried recording much longer than that (no reason to try, really), but at 2 minutes it had spanned at least once and the buffer was still looking fine (hovering between 1-2 *) so I'd expect it to keep spanning OK.
Even if you can't push 1728x972, I'd imagine that you could still push 1600x900 which is still at least a bit better than 1280x720 - especially if you crank your stills quality down to jpeg.
