bayonetta 3 is gonna be console exclusive to nintendo, because they ponied up the dough to develop it in the first place. in general though, "console exclusive" is a dead concept, as you really need to tap multiple platforms to get your profit margins- note almost every single "exclusive" xbox and playstation have now either release on, or started on PC.
I have a decent gaming rig, and honestly i've never seen much reason to get any console but nintendo as a result. i get to play the games with mods and a better ability to controll what kind of people i end up playing with online.
