I highly doubt it

The engine is a PC engine, hence it is coded for 1 person playing on 1 system, not 2-4 socialising in the sofa having fun. Maybe the next game, if Crytek focuses a bit more on consoles, but Crysis 2 is more of a PC game and hence console-features like splitscreen is not plausible.
To bad, since the console could handle it if coded, but I doubt the engine can.
