Gamestop is basically gonna allow you to trade a 360 copy of BF4 for an Xbox One copy for $10.
Mixed feelings here. I guess if you are so anxious to play the game that you don't mind paying the $10 rather than waiting X weeks for the Xbox One to come out. I doubt that your stats/progression will transfer so it'll be like starting from scratch again, just with some game experience. Also, is there any special map or give away for BF4 for pre-ordering on the Xbox One (like Ghosts' Free Fall map). If so, I'd be curious how gamestop manages that.
For me, it kind of depends on when the console will be released. Will we have to wait 2 weeks, 1 month, etc?
