Huang recently stated that nVidia would not use Global Foundries as 'it's AMD's fab'. It's already starting to look like TSMC's 32nm node might be just as horrible as their 40nm node already is, if that is the case I would think nVidia would be smart enough to use Global Foundries (assuming their 32nm node is good) for at least some of their production, even if it is 'AMD's fab'.
