No video (i personally never take video)
So put this camera where the 7D use to be at 1500, now when the 5DX comes slot that at like 2500 and then drop the 5D2 completely or price ijt at like 1200
No video instantly kills the market for that camera, and makes it impossible for Canon to sell it cheap. You want them to use a sensor they've already made (keeps cost down), in which case, video costs them nothing to add in. I can put video on a 50D, which wasn't sold with it, so it's clearly just a firmware/software addition. There may be a few hardware pieces to make it look better, but ultimately, it's cheap if not free. But, having it means way more people buy the camera, which means the cost of manufacturing is cheaper for Canon (offsets R&D, etc over many more consumers). Taking it out would definitely not offset the sales loss.
I agree that the body would have to be 60D like, the AF would probably be the 7D one, but I don't think they can put 6FPS in it, even if the camera can handle it. It'd have to be the same FPS as the 5dII. Even then, it probably still retails for $2k. I'd basically expect a 5dII with very slight improvements that allow them to be manufactured cheaper.
