Exact quote is promising
In multiplayer, we’re delivering the epic 64-player battles that consoles players have been asking for. On Xbox One, the game will also be running at 60 fps without sacrificing the features that makes “Battlefield” great – all-out vehicle warfare, destruction, huge maps, and team play.
Kind of almost makes it understandable why they're not hitting 1080P, at least in multiplayer. 64 players+60FPS= hugely demanding.
