After reading Carpeteria's post on the child-like text on the cardbacks, you may just be on to something here Ed. Maybe Hasbro IS totally gearing these things towards kids who are watching the DVDs for the first time, and not wanting to spoil the Vader/Luke father/son relationship for them. That's be pretty funny, and kinda pathetic if that's really the case here, but it might just be.
Lame.
