this preview has some cool new info (i think its new anyways).
it states for galatic conquest that there are neutral planets and planets designated to certain factions (like kamino to the clone army). neutral planets have two maps to battle on, where the planets designated to certain factions will have only one map and if the faction that owns the planet loses the planet is lost forever.
x-wings can hover.
kamino gives a 10% respawn to their reinforcement bonus for the republic.
genosis gives a bonus to reinforcements for separatist
mace windu and count dooku will be availbile for a.i.
pilots piloting ships will cause a slow regeneration of health and they auto-eject from ships that are about to blow.
also for single player, you can command your a.i. that are within a certain radius of you.
not sure if that is all the new info in the article, its a good read with a lot of quotes from the producer, Jim Tso.
