Rather than waiting for the WiiU, why don't you just buy a PS3 now? You'll be able to play Arkham City and a whole lot of other great games.
Doesn't make any sense to buy a next-gen console only to buy ports of games that were already-released.
I didn't own a certain gen console myself. So rather than buying a ps3 then a wii u, which happens to have a game I like,
I'll just buy one. Basically it doesn't make sense to me to by a certain gen console for one game when next
gen console is right around the corner. I played off others console around the house, that how I manage to play and buy games on all consoles
without actually owning them. I want my own console.
