Lots of sites say "confirmed by [other site here] but when you go to that site, there is nothing there that smells of confirmation, but references to other sites bitching about the same thing. It's a giant circle-jerk where its given credibility because so many sites are talking about it.
Some dude is laughing his ass off somewhere, probably having won a bet that went something like this:
Guy 1: "Hey, I bet I can get all of the fanboys freaked out by making some bogus clips and claiming they're legit"
Guy 2: "No way, nobody's gonna believe that"
Guy 1: "Ok, 6-pack says I can."
Guy 2: "You're on."
I have no doubt that Lucas has added some shit that I will hate. Of that I am 100 convinced, but I'm equally certain that these clips are complete fakes.
And before I get accused of being a Lucas apologist, I haven't pre-ordered my BD set. Why? Because he still has to prove to me that they're worth buying. Ironically, the set I'm guaranteed to buy? the PT. that's fucked up.
