Last time I checked Microsoft didn't have the rights to SONY and Nintendo's exclusive franchises and you'd be hard pressed to find 1 good exclusive in the past year on the 360 let alone 5.
With both SONY and Nintendo you can make a distinction, can justify both of the strength of the exclusives.
Microsoft has 2 known games and an online service that allows you to talk to people in different games...
how quickly you stans forget that ps3 saw no "good exclusives" for the entire year of 2012. The only reason we're getting them this year is because they weren't able to finish them for Christmas 2012 like they were trying to.
