There are no images yet from a production camera, but you can be pretty certain that ordinary images will be the same.
The advanced features are the upgrade points. Better autofocus, much faster liveview focus, wifi, touch screen, and the much faster and more powerful Digic 5+ processor. It also takes SDXC UHS-1 cards which write at twice the speed. This is a sore point with the slow cards.
Unless these features are more important to you than the $$$, invest the savings in a 60D and put it into a good lens.
Still, with no AFMA, I'll be passing it up.
