I'm still trying to decide when to switch my Ghosts and BF4 over to the Xbox One, though the closer I get to the release the more I want to switch immediately.
Ghosts, I will most likely trade in for the Xbox One version on release. I hope there are at least a few CAGs in the same boat so that we can do some "clan wars" games. Ghosts graphics should be improved but the gameplay should be very similar.
But, I'm in the clan for Battlefield and this is the tougher choice. I'll still have BF3 on 360 to play. Battlefield gameplay is going to be soooo different on next gen and it's really too hard to resist. 60 frames per second compared to 30. 32 versus 32 matches, rather than 12 versus 12. First to the Second Assault DLC. If BF4 on 360 wasn't so messed up with getting a squad together and the game freezing, I'd be tempted to stay 360 for a bit longer. So, another week of 360, then I'll pioneer the next gen, and save some seats for you guys.
