Quoted from Taygeta:People not wanting a game to be remade so they can sell theirs at a higher price will chime in and say "they'll never re-run it (buy mine instead!)". Usually with bogus claims about rights, licenses whatever. Happened with IM, SM, AC/DC etc etc etc. Tron is about as cheap as a game as they come from a BOM standpoint. They'll rerun it eventually.
They have good relationship with Disney again (SW). A TronVE is not out of the realm of possibilities.
