As someone who has been reporting these news stories and finding out more, I'm extremely wary of what will actually be playable on Wii U this year. Obviously Nintendo will have some cool ****, but more and more, I feel like it'll be the same ol' third party crap and excuses we always get on Nintendo systems. :(
I mean, it's likely that all Wii U demos will just be at Nintendo's booth. Hopefully third-parties will be present there. Who knows...
