If you have to use crap ass origin on the nexbox count me out. That would be a deal breaker. I highly doubt BF4 would be xbox exclusive when COD will destroy it being multi platform, EA in the right mind wouldnt want to give it up that easy or stupidly.
It has to be early DLC or some dumb thing like that.
I am looking forward to see what M$ is going to be doing next though.
