I'm going to be very scared if mobile gaming gets any bigger, mainly because of the lack of "big" games. Ironically, I can't seem to play games that are meant to be played in small chunks, even though my attention span should probably be more suited to those types of games. Most games I play are RPGs and fighters, and fighters control like crap on phones.

As for exclusives, it seems that trend is mostly dying, at least on Microsoft's end. Microsoft right now just has GoW and Halo, which do push millions by themselves, so it's not like they need any more than that. But Nintendo has Zelda, Mario, Metroid, Smash Bros., and all the ones you expect from them, while Sony has Sly Cooper, Ratchet, Infamous, Uncharted, Twisted Metal, LBP, etc.

I'd rather have the Steam model or games on disc rather than have phone games take over everything, which is something I really fear.
