Ain’t It Cool News has some new details outlining the plot of the Tron sequel. It goes without saying there are spoilers aplenty, so don’t click through unless you want to be spoiled.
It sounds like they are still trying to decide on the title for the movie. It’s not likely to be TR2N or Tron 2.0. Whatever they call it, at least in online circles TR2N is shaping up to be Disney’s most anticipated future release and it doesn’t even open until 2011.
