I don't think that's the definitive evidence you hope it is. The Wii U version was an inferior port to the PS360 versions, which correlates very much with what the anonymus dev is saying. Vigil Games saying some nice things about the Wii U prior to release of the game is hardly surprising as they're trying to sell a product. They're not exactly going to admit they had huge trouble making the Wii U version reach parity are they?

Many devs have said that the difficulties of WIiU are the ways and extra work and money required to implement the Gamepad, Miiverse etc. features. Nothing to do with the HW itself ....well yeah but not the chipset
