Lucas seems intent on upping the ante with each consecutive "final battle" scene: A New Hope had the solitary focus of the Death Star battle, The Empire Strikes Back had Luke fighting Vader while his friends escaped from Cloud City, and Return of the Jedi had its epic battle of Endor waged on three fronts at once. So nothing less would do for The Phantom Menace than to have four simultaneous conflicts on Naboo. The Gungans versus the droid army, the starfighter assault on the Federation battleship, Amidala's attack to capture the viceroy, and the two-on-one lightsaber clash between the Jedi and Darth Maul (2).
Ep II regressed to a final battle on one front, moving from the arena out into the open and finally to the hanger. But it succeeded in 'upping the ante' nevertheless by being the BIGGEST battle spectacle yet. Ep III promises to be summo grande and multi-faceted, with the "final battle of the Clone Wars" (from the Star Wars website) and showdowns between Dooku and Anakin, Bobba Fett and Mace Windu, and Anakin and Obi-wan!
