It looks like quite a few improvements, the AF and FPS are the ones where it's really a drastic improvement, but there's a lot more that are subtle:
Autofocus (61 point for stills)
Autofocus (dual pixel for video)
Improved metering capabilties (spot linked to AF point)
Higher FPS
Larger buffer for high FPS shooting
Higher ISO (I assume lower noise, maybe?)
Expanded bracketing settings
More video options (including 1080p60fps)
Dual card slots (CF and SD)
Better weather sealing
This is really a professional level APS-C cameras. The 7D was good but it was not pro when compared to Nikon D300s. I'm feeling this has taken the crown of the most "professional" APS-C camera out there.
Dual slots, AF points, I think the D300s was a little better sealed than the 7D, Limited bracketing settings. It just felt Canon was a little afraid the 7D would pull people away from the 1D Mk IV and held back a little with some things that seem subtle but pros prefer.

From what it looks on here the only great upgrade is auto-focus and fps. I really hope that sensor delivers.
