I love my Wii U, and I don't want to see it turn into a Nintendo only machine, so I'm supporting most of the third party games. I already bought Rayman and Splinter Cell, and I have Arkham Origins and Ghosts preordered. I'll be picking this up, as well as AC4, too.
Wii U. Still surprised they haven't shown anything of the Wii U version. Let's hope Ubi isn't being lazy and will actually put effort into it.
All i'm hoping is that they make the version the same. I know a lot of 3rd parties haven't been quite so courteous lately.
