Not to mention you play as Vader's 501st Legion. The troopers that storm the Jedi Temple, who board the Tantive IV, who do practically everything with him. His personal elites. In a single-player spanning from AOTC to ROTJ. . . PWN3GE!!! And you get to play as 3 different Anakins. AOTC, ROTS Anakin/Vader, OT Vader.
The greatest part of BF was being able to play as a random, average, anonymous soldier.
By throwing in the whole Jedi/Sith think, it'll just be like playing one of the Jedi Knight games with an army at your back. Not saying that's a bad idea...I'm just saying that's not BF.
That said, the ship-to-ship combat will kick ass.
