The company has not yet said what, if anything, will be changing from the 360, PC and PS3 versions.
We haven't heard much about game development for the Wii U yet, but Ubisoft has confirmed that it's going to bring 'Assassin's Creed 3' to the system. What's particularly interesting is that they said 'Assassin's Creed 3' and not just 'Assassin's Creed,' which seems to say that they're bringing over the full game and not just a similar game set in the same environment.
It's going to be really interesting to see what happens with the Wii U version and what kinds of controls are used. Hopefully we'll see more soon.
