If they do implement this I would imagine that each player will need an account due to the game being only online and there is character, weapon and item progression just like borderlands 2. Where you need to create a character on a second account on the same console. But then again your character details could be stored on line then as long as the console has the game installed and you all have an account the in theory you could have split screen.

Thanks that does make sense and it does seem viable.
