i hope anakin uses both red and blue against obi wan , starting off with blue one , throughout the duel obiwan keeps trying to talk to him to make him stop using the name anakin , then anakin does stop fighting and says "that name no longer has any meaning for me , i am darth vader" (or something to that effect) then he ignites his blue saber AND his brand spankin new red saber and continues the duel during which obiwan cuts off anakins real arm (blue saber) but he continues to fight with even more fire and viciousness with the red saber before taking the plunge , as obiwan is leaving he sees the severed arm with the blue saber and he takes it , thus showing us how he got the saber AND also showing us how obiwan knew that vader was really anakin , you may now all tear my dream to pieces if you wish but i think this would rock
