I REALLY want the next BF to be the 2142 successor, titans and everything. There were hints a few things in BF4 near the end, so i'm hoping that's what we'l get.
I really hope not. I don't want futuristic weapons (and potentially more click to kill skill free weapons than bf4). And there's titanfall anyway.
Something set in the Korea/cold war/falklands where there isn't too much gadget spam would be more fun IMO.
