Ok point taken, you're right. 

Although from the same article "But there are gripes to consider before jumping in bed with the Wii U version. Most significant is the degradation in texture quality, the muddiness of which matches the 360 release without its HD texture pack install. Surfaces can look flat compared to the game running on PS3 and 360 with full installs, and the lack of any similar optional install on Nintendo's platform means pop-in flares up while in wide outdoors areas. Curiously, in terms of sheer playability, Sony's hardware achieves the most consistent frame-rates during combat, with 360 taking middle ground here, and the Wii U suffering from more regular dips to the low 20s, perhaps explaining the omission of split-screen gameplay." 

So it's not all that rosy.

Don't get me wrong, I don't want to argue that Wii U is inferior to PS360 cause it is not the case, but especially since it also outputs to the gamepad, I think that the difference in visual quality will be marginal, especially with straight ports, not highly optimised for Wii U which I still belive wouldn't make that big of a difference.

worse than PS4/X1 but better than PS360

Right, I'm just saying the title was misleading for the thread.  I kind of expect a next gen console would look better than last gen.
