Intel will definitely be fine, I think the real effect will be on nVidia. Currently nVidia throws a lot of money into its TWIMTBP program which rightly or wrongly helps developers optimise their games to run on nVidia hardware. The current effect of this on how games perform on nVidia hardware vs AMD hardware is a bit unknown, through the Batman: Arkham Asylum anti-aliasing fiasco does seem to indicate that its borderline anti-competitive at times.
With all three consoles on AMD hardware, developers will not have a lot of choice but to optimise their games for AMD hardware, making nVidia's TWIMTBP program useless. I'm sure they'll take the money, but developing a game that will be less than optimised on AMD powered consoles (which generates the most money) doesn't make sense. The end result will probably be good from a fairness perspective, and hopefully force nVidia to compete on hardware alone and not game optimisations that have been proven at times to deliberately disadvantage AMD hardware and the gamers that use them (disabling GPU powered physx when an AMD and Nvidia card are both installed in a PC, as an example, even if the nVidia card is used to power the graphics).
