Xbone being the weakest system will probably look the worst/have the most framerate issues.
Think so? Skyrim wasn't that bad on xbox 360 perhaps?
Xbone is not the 360. Xbone is the weakest system out of all that will have this game. You have to remember, that unlike skyrim, this game is shooting for 200 players on screen. Sacrifices will have to be made on the consoles.
The need for a separate keyboard and console-exclusive headset all add up. I'm pleasantly surprised on how much can be added on the PS4, haven't seen too much xbox one (only two people I know have one). I'm no expert so I can't say for sure but we'll know when June gets closer.
