If you have the type of computer that can handle it, I say go for it. Personally, I'm going to play it because my computer has at the decent lowest level settings on it to get the game. I mainly want to have it for the PC because of the freedom you could do with it compared to consoles. With consoles, you only have so many buttons. With the PC, you could pick your poison what keys you want assigned to what.
Also, you have the flexibility to use the controller on the PC IF, you so choose. Where as you have to use the controller on the console and all I can say to that is: You better hope that thing isn't bulky and painful, like SOME controllers I know. (I'm looking at you Xbox.)
Finally, the last reason I have for going to PC are the mods. You seem to get more bang for you buck when you can have the nearly unlimited amount of space on your computer to get any mod to extend your game play.
