With the PSNow price ($49.99) leaked, who will pay the extra $49.99 on top of PSPlus? Will you cancel your PSPlus and get PSNow instead? Will you not get either of these services and just enjoy the games on the PS4?
Personally, I'll just stick with PSPlus. My PS3 works fine and I still play a lot of games on it when not playing my other 4 game consoles. PSNow also isn't going to have a lot of games for it immediately anyways. It would probably be best to wait a year before signing up for it if that's what you intend to do. What does SW gamers think?
