tinyE: *ahem* The Emperor would have died regardless and without him (most likely Vader as well), and while the battle of Endor would have been a tragic defeat, the Empire still would have been a lame duck and the rest of the War would have been a cake walk for the surviving Rebels.
nightcraw1er.488: Would he now. I think if the Ewoks had chosen not to side with Solo, Luke would have felt the waves through the force, and knowing his teddy bears had abondoned him collapsed to will of Vader and the Empire, thus leading him to join the dark side and the empire went on to reign the universe for a millenia, all because of the Ewoks, mwwaahahaha.
nightcraw1er.488: Good point.
