And the Wii U likely doesn't have a GPU as powerful as a HD 4850 that is over 4 times as powerful as the X360's Xenos which would certainly be dramatically outperforming IMO. 

Partially correct.   Many people early on suggested the Wii U's GPU would be based on the HD 4770 which is only slightly less powerful than the HD 4850 (960 Gflops vs 1000 Gflops).

I myself still believe the HD 4770 is likely given the power consumption benefits and currently active die process (40 nm).

personally I doubt that there will be a direct parrellel to any existing R700 SKU. It will be a custom chip likely with a whole bunch of EDRAM.

Certainly all console GPU's are custom but they tend to be built from a specific model's groundwork.   Even a simple clock change would be enough to call it a custom chip.  It simply needs to be something other than the absolute default.  How much AMD customizes it is another question but their is no question that it will be based on an existing GPU.
