I never got early access last time so can`t remember the how the fiasco went. Was it a mixture of people not having the codes plus server issues?
I was hoping for a BC game as a launch title for the next gen. Mind, when the 360 was released it was as powerful as the PCs at the time, so if the next gen follows that maybe we'll get the same number of players as on PC for BF4.
We should get the current level of players though, 32 on each side. From the proposed specs I've seen for the new XBox it should be able to do more than the top end PCs could at the time that BF3 was released. I'd be happy with 24 players each side and 60fps and like you, I'm not sure I'd buy BF4 if it's on current gen. Next gen only for me.
