They apaprently have been signed on for 6 years of Lost.... honestly I think that's WAY too much for a concept like that. What does that equal? Say 24 episodes a year, at 45 minutes a piece....108 hours? You'd have to start making up the dumbest crap to sustain a story that long. Personally I don't want to waste 108 of my hours... just watch the last finale 6 years from now.
