The SW figures... Just a quick feel of the head would basically tell you who you have, 99% of the time.
With clone repaints, I think those odds drop to around 75%.
While I don't mind the blind packaging for most lines (Lego, Kre-O, etc.) due to the lower prices and relative lack of repetition, I would be annoyed if blind boxed Star Wars (or any) figures became the norm over here. At $6+, I want to know what I am getting, especially since I own so many of the characters already.
If Hasbro wants to try something blind packaged for the action figure line here in the States, I think small characters/droids (Mouse Droid, Salacious Crumb, Nunas) or accessory packages (like the Legends Clone lockers) would be neat. Otherwise I hope the blind packaging will remain an overseas novelty.
