Apparently the Tron 2 trailer surprised a whole bunch of folks down at Comic-Con yesterday. I can't find the trailer online as yet, but there's a fairly detailed description here. Details are sparse, but sounds like Jeff Bridges is on-board for the sequel.
I just bought the 20th anniversary collectors set. It has a bunch of stuff on there about how they made the movie. I knew it was cumbersome but I had no idea how hard it really was. There's a reason that film is the only one of its kind.
With technology today it should be much easier to produce a sequel. Hopefully of quality, as most people today have some knowledge of computers as opposed to the era of the original.
