Here's another video that won't exist long, because it was meant only for the eyes of those who attended a weekend convention of comic books and other nerdy entertainment. Disney's preferred method of dispersing TR2N information is through word of mouth, with Con attendees telling non-Con attendees, "Jeff Bridges was totally in it, and there were those sweet light motorcycles just like in the first Tron, or like in the Tron arcade game, but without the part where you have to fire upwards at the MCP cone. Also, it was called 'Tr-two-en' for some reason." But if you'd rather just see it yourself, here it is.
