You are wondering why it's PC exclusive? It's UE 4, it's Directx 11, current gen can't handle that. It's as simple as that, after next gen comes they might put it consoles too.
@Daian true epic said you need some serious horse power like a gtx 680 to run the engine nicely, epic was complaining about how next gen Xbox and PlayStation will have trouble running it and they ask why its a PC exclusive lol.
@Daian Actually its because they didn't put in any scripts for current consoles because they don't see the need....yet....like frostbite 2 wasn't supposed to be for current consoles but they did it anyway because next gen consoles took too long.
@zulwalks exactly the ue3 is ue4 on steroids which needs a gtx 680 to run as per epic. the current consoles already run ue3 with high efficient code to optimize the visuals to the limits of current 6 year old hardware.
