Sometimes these threads feel a bit like US politics in the media, where there is apparently a need to present "both sides" of an issue even if only one is viable.
This argumentation is wrong for not just 1 but 2 reasons:
1) For what you said to stand, the Wii U version would have to be equivalent or better than both the PS3 and 360 versions, not just one of them.
2) It is in fact worse than the PS3 version in terms of framerate, though not quite as dramatically.
There are no "weird blurring effects" on the 360. Wii U renders the exact same resolution with the exact same anti-aliasing method. At a lower framerate.
At the time of the statement, I was unaware DF had done a review, so keep that in mind please.
1. I said Wii U and 360 were identical (this was again based off first hand impressions as I saw them running side by side in multiplayer, because that is what my friends and I play.)
According to DF, PS3's version is inferior, though it's framerate is higher, while Wii U and 360 are visually identical.
2. I think the average framerate is a few frames less than PS3's, and ~8 less than the 360's, here is the thing though, I was basing what I said off of multiplayer.
The multiplayer game is for all intents and purposes the same game, from this review, it's clear that Wii U has an inferior port to the 360, however, if all you were to play was multiplayer, as I had, you would figure that Wii U is identical, and you would think that co op was pretty good.
Considering they took the 360 code and implanted it into the Wii U (paraphrased from the DF article) it's not a bad start for a launch console, but yes Wii U isn't going to match up with PS4/XB3 which would play 360 code likely without a single drop in frame rate and would improve visuals with likely at the very least resolution and maybe a solid 3D effect (since those devices don't exist though, it's impossible to say to what extent they could simply take 360 code and improve upon the game, seeing as how PCs don't look drastically better with their ports of console games either)
I don't think we disagree on the Wii U either, I'm just more optimistic maybe.
