Also with the GB article stating that Sony are giving developers strict guidelines for some of this stuff I think its very possible that fps parity for multiplayer could be one of them.
On the other hand though, this could just go back to my PC comparison. That doesnt have multiplayer parity at all for fps and works just fine.
Either way though this announcement doesnt bother me in the slightest. I will stick with my current PS4 and will be happy for the people who feel the need to upgrade because they've been given that option without taking anything away from my gaming experience.
