I looked at the images at Imaging Resource and they look just like images from any other Rebel i have owned.
I might see a difference when pixel peeping but it´s sure not breathtaking.

Taking a hurried peak, it seems like the gain vertical banding issue of the 7D may be entirely gone. It's hard to tell because the 7D2 has such a small black outer frame area in the RAW and none of the shots are close to lens cap shots, but there is a chance they got rid of all or nearly all of the offset banding at low ISO all together. So that is the very good and impressive news.
The bad is that the random read noise still shows no improvements since 2007 whatsoever, as far as I can tell. It seems like it will be extremely close to the exact same DR as the 7D. The read noise might even be a touch higher than on the 7D. Not quite sure yet, didn't locate quite the proper 7D file or my old numbers. Without the banding, the effective usable DR should be higher though.
