As much as the EA/MS closeness stinks of cumstained cash, and EA generally suck quite a lot - their timed exclusivity deals are going to seem important for a lot of people IMO. Garden Warfare has a lot of style, I can see that cash in working... Titanfall looks amazingly fun. FIFA looks meh, but you know people are gonna buy it.
Xbone has some decent software coming. Shame about that price!
