The Xbox One with its extreme anti-piracy status is going to completely backfire.
Always-online statuses and this extreme block against used games is going to not only kill GameFly and other services, but give reason a people to pirate in the first place.
Note: I don't condone piracy, but that's just how it works. People hack their consoles to get around certain things in the first place. The 3DS? Noone wants that region lock. The Wii? Same reason: region lock.
The Xbox One? Not JUST a region lock, but now people will hack it to play used games!
