Dont think that the campaign content would really allow for that depth of complexity, throwing a third faction into the mix could be pretty cool though. Maybe on the XBOX720 / PS4 they could allow for multiple squad battles, 3 or 4 factions fighting at the same time with a greater array of simultaneous objectives that dictate the flow of the battle. Would be awesome if they could pull that off, so that each match has the ability to take multiple directions.
