Nah, I think it's more important for Sony to go "Guys! look at these sweet games! Go buy PSVR!" than it is for them to have an even bigger game advantage in 2017. I say that because I seriously doubt MS is going to launch more or bigger exclusives in 2017 than Sony will.
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.
