Man these sound great! I've only owned 1 Castelvenia in mu life, but if this one has co-op i'm all for it! Man my 3rd party selection is going to be huge within the first year! Already I want Aliens, Darksiders, Batman, Rayman, right off the top of my head. As long as it doesn't get terrible reviews I can't wait!
As for the Wii U street pass oh please please please please please be true!!!!!!!! When I realized how cool the Street Pass was for 3DS I thought is there a way they could do it with Wii U? It seemed difficult and kind of odd, but if they have a way then I am all for it!
Once I street passed a guy and later I found out he crapped himself when I tried to race my MK7 Airship Fortress record! It felt so good! I want more feelings like that with Wii U.
