that would cool if that was to happen as I have friends on xbox I would like to play with but would rather play the game on pc for mouse and keyboard .
But activision are greedy ***** and will probably make you buy it for each platform you want to play it on.
I know people who can pretty smash average keyboard/mouse user while using pad,and in Division we have person from OCUK who uses pad and has 2k hours and he is very good,even tho he is on PC,just uses pad
Nothing to do with Activision here,more like technical problems with all cross play thing i think,i bet Activision would be more than happy to sell this game on all platforms if it has cross play
