I see. But because they're maintaining datacenters for PS3/PS4 streaming I think they have the potential to go hosted, at the end of the day multiplayer servers are developer-controlled and network servers (e.g.: PSN, Xbox Live) are mostly identity services and such. (Even matchmaking isn't the network's job anymore)
