Besides exclusive content (which could only be cosmetic) I do not think they are being treated too different. The PS4 is new (hardware, PSN service) all foreign and never has bungie released a game on it. The only reason I see bungie opening the beta sooner to the PS4 is to have more time with the new toy, learn more about the potential issues and Bc it activision knows COD sells more on xbox why compete with yourself when you can own both systems? Look at BF4, the servers on the PS4 and Xbox one we murdered everyone made a big stink about it.. PC? Perfectly fine. I'm not going to pretend that I know about servers like that but I'm sure the fact that BF being primarily a PC game for years makes it easier when a game is released. My 2 cents :)
