PC and either Wii U or Xbox One. I'll probably end up buying it on whatever console I don't use my backer copy on, anyway. XD
PC(Windows) because it'll probably be the "best" version and I'll hopefully have my new PC by the time it comes out.
Xbox One because that's my main console right now.
Wii U because that just feels the most "right" because of Rare's history with Nintendo.
No, not all Xbox owners are dudebros who love grey-and-brown PvP FPSes. Please feel free to quit stereotyping now.
