I'll probably be getting a PS4, but not right away. Maybe a WiiU if I end up having the money and they release DS and 3DS games on the estore. I may get a few more games for my 360, as well.
But I have a really, really good computer (i7 3770, 8gb ram, GTX670), and if the game comes out for consoles and PC? I get the PC version. Even if I have to wait (I'm looking at you, State of Decay).
In a lot of games I prefer the controller, as my hands are quite arthritic, but I have to have the customization and I can't shoot worht a damn with a controller. So if it's Mass Effect or Skyrim, or any game that involves aiming... PC it is. And I can also use a controller in many PC games if I want to, anyway.
Edit: I love RPGs and some games are worth buying a console for, like FF and KH. I won't limit myself to one system... but I think I will stay far,f ar away from the Xbone on principle.
