On the IMDB message boards, an anonymous poster claims to have seen a new Tron Legacy trailer at the Cinema Expo in Amsterdam. Of course, this could all just be bullpuckey, but folks at Collider think it may be legit.

Here's the IMDB post:

I went to the Cinema Expo in Amsterdam today where Disney gave a one and a half hour presentation about their movie projects of the next 18 months and the presentation ended with a 6 to 8 minute presentation about TRON Legacy.

I have to saw, my mind was complete blown to pieces! MY GOD this movie is the most stylish, designer, innovative movie projects I've seen in a while, certainly from a studio like Disney. We saw plenty of concept art and animatics but the presentation ended with what looked like a new trailer. It was basically an extended version of the previous trailer. We first see Sam in bed as a child, with Kevin sitting on his bed, talking about an experience Kevin has had, and we see toys in Sam's room based on elements inside the TRON world. During these scenes you never see Kevin's face, he's only seen from the back. Then we see the entire introduction of Sam looking for his father, discussing his disappearance, going to the arcade, sitting at the table with the laser behind him, but instead of a fade like the first trailer, we now see a neon blue pull of the outlines and figure of Sam into the camera. and that transports us into the TRON world.

Mindblowing imagery, but the music. DAMN people! I need that soundtrack in my life right now! The song playing was completely new and it literally shook the room and made my inner core tremble. I featured a VERY hard and deep bassline, repeated constantly with four or five synth tones playing over it in repetition. The bass really shakes you up like a very hard and loud drum. It's just so innovative as a soundtrack and really does fit the atmosphere of the movie.

Back to the trailer. We see Sam walking around in the TRON world. Looking around as recognizers fly past and eventually a shot where he is lifted up into the disc game arena with about five players facing eachother to battle. Two players go at it and one of them throws his disc straight through the other player which leads him to shatter like glass and break apart into thousands of square pixel type pieces on the floor. It's epically beautiful in terms of art direction and mood with all it's neon, black and lighting. Really cutting edge, modern and also retro to some degree. We see some shots of Clu2.0 at the end of the clip we see Sam facing Clu2.0 who is a digitally rejuvenated Jeff Bridges which is EXTREMELY mindboggling to look at. Really well excecuted! Sam stands in a room looking at Clu2.0 and says: "Dad?", Clu2.0 looks back and says: "I'm not your father but I'm certainly happy to meet you", then he turns around and starts to walk away. It's all VERY powerfull stuff, with some awesome footage of lightcycle battles with 3 bikes cutting curves, bumping and crashing into eachother.

I'm REALLY psyched about this movie right now and the trailer is STUNNING, I seriously can't wait to own that soundtrack and play it to death. EPIC!!!

Just for reference, here's the original teaser trailer:
