It seems like the rumor has been spreading for some time, now, but I just found out about it. In what is probably the geekiest move of the year, Disney is making a sequel to Tron. A trailer of the so-called Tron Legacy was recently shown at Comic-Con. Both the trailer and the official website state that the movie will be available in 3D theaters but the trailer looks good enough in 2D so I doubt it will only be available in those.
