Re: What console?
"Should I be replacing the PS3 with an Xbone or PS4?"
I wouldn't bother. The graphical improvements while noticable really arn't enough to make it worth the expense of buying a new machine and new games. IMO obviously. YMMV. I'm waiting for the PS5 when the graphics - hopefully - will be a quantum leap away from the PS3 rather just a few baby steps.
