I think the 3.25m Asynchronous Multi Player goal could turn out pretty cool.
And for those of you curious: WiiU is now officially just another choice like XBone/PS4/PC. If you pledge for a copy of the game, it can be picked when you submit the survey, no special tier necessary.
I imagine they'll do something similar with the Vita version assuming it gets funded, though maybe not. Vita's a powerhouse, but who knows if they'll be able to port the game directly or if it'll be stripped down (and thus, presumably, cheaper)? Either way I don't have a Vita and don't currently plan to get one any time soon so not really worrisome to me.
