Okay! lets look at the list...Actually, is this only 2015 games? Or is it any released/upcoming exclusives or partial exclusives? Hhhhmmm....I'll go with just 2015 games...
PS4: 12
XBO: 3
Bet with Adamblaziken:
I bet that on launch the Nintendo Switch will have no built in in-game voice chat. He bets that it will. The winner gets six months of avatar control over the other user.
