I dunno, but I just don't want it to. It feels like it should be a console game and nothing more. It just feels that way to me.
Plus, if it does go to PC, the games for the consoles will feel completely inferior due to the things PC people will be able to do like modding *cough* Skyrim *cough cough*. I just don't want it to be 'that' type of game.
EDIT: Jimmies have been erternally rustled.
It wont for one simple reason pc players have higher standards and with the current businesmodel and zero patches and lack of content none would invest in it.
