Naa, it will be most of the weapons from Battlefield 2, 3, 4 and Hardline plus maybe one or two more; Likely to include a couple more vehicles; Multiplayer modes will include Conquest, Rush, Team Deathmatch, Squad Deathmatch, Domination, Obliteration, Defuse, Air Superiority, Capture the Flag, Carrier Assault, Chain Link, Gun Master & Squad Conquest; Expect 4-6 DLC packs with extra maps and character skins, extra weapons and new vehicles; Expect a Metacritic score between 79 and 89; Gamespot and IGN will score it 8.5/10 on average
I literally died inside thinking BF5 is the next focus (as I did when BF4 was in development to be followed by Hardline, goodness I might just be a member of the undead at this point). Just give us Bad Company 3 (I feel like I'm becoming one-note every time I mention), but lest we forget, DICE don't know why Bad Company 2 was beloved. So yeah, there's that.
I'd actually like another BF 2142, I liked the modes and futuristic stuff in that one, and I think that with today's technology it could be something quite cool. But then again, it is EA so they will find a way to screw it up somehow.
I don't think they would go straight to Battlefield 5, either a brand new brand of battlefield or a sequel to 1942/2142/Bad Company
