I just saw it on tv and all I can say is WOW!!!!
And I've had some pretty serious problems with Kazaa. I would download a song or a trailer, then go to play it and my whole computer would freeze up. Sometimes it would freeze up when I would try to delete the same file later. Then it started causing random errors on other programs. It sucked.
About 5 months ago an Episode II preview surfaced on kazaa, I think the one you mentioned. It is pretty cool, especially the 4 Mandalorians and the Braveheart-like Jedi rush (so many lightsabers...damn thats cool!). But this is a different preview than the trailer running before Monsters inc...the new preview has no sound except for Vaders breathing and some lightsaber sounds at the end. Lots of quick shots of different carechters, just enough to get you pumped for more. Very cool stuff!!!
