http://www.shacknews.com/article/73798/luigis-mansion-2-for-wii-u-spotted-at-retail Nothing but rumours so far, but definitely interesting.
Never played much mario after snes world *shrugs* I could see the whole "cross platform" thing being a possibility with something like that, like using the 3ds with the wii u etc etc... super gameboy and gamecube with gba stuffs. ...anyway mostly just wanted to say nice avatar
I loved Luigi's Mansion. A Wii U version of Luigi's Mansion 2 would be cool, as long as it isn't just a port of the 3DS version.
If this is a straight move of the game, then it doesn't make much sense since I thought the whole reason LM2 was on the 3DS was because LM was original envisioned as a 3D game. If anything, I would imagine it'll be a different version and the two will have cross-play so Nintendo can have something shiny for 3DS owners/early Wii U adopters to tinker with.
