Tron 2 Renamed, Plot Revealed

TRON 2 has been renamed to TRZ according to trade paper Production Weekly and it also has a brand new synposis that goes like this; After being transported into the surreal landscape of a mainframe computer to destroy an intruder (Tron), a programmer finds himself allied with the leader of a rebellion against a corrupt cyber-entity.

I never watched the first TRON and the trailer that was shown at Comic Con did not impress me in the least. The big shocker for me is renaming Tron to TRZ. Whats the logic? You lose the draw of a known name when you turn TRON 2 into 'TRZ'.
