I have a PS4 i love and play 90% of the time and Xbox one to play with a couple of my mates who still dont like the Dualshock 4 they say it is not good enough(it fucking well is), but if i could play all 3rd party multiplayer games with my mates on PS4 via cross platform play i wouldnt need the Xbox One yes i would miss Gears of war, but not Halo as it is now dead to me, but i could sell the xbox would save money not having live subscription, so who out there who owns multiple consoles would do the same?
