anyway, I await for whatever is coming my way from GAF :/
I feel you, I own both consoles and so far I would say BF4 is one of the games the visual difference does make an impact on PS4... yet at nights I play it on the xbone because the PS4 noise its just to annoying. It may be my unit is defective, but honestly I hardly think so, like what defect would make it to be this loud anyway? I think its more a design issue.
