I have a theory that the island is outside of time. Also, the show isn't only about getting off the island anymore. It's not the island that's making them lost. It's not being there that makes them lost.
Did you guys notice when they show trailers and stuff, in the letters of LOST, there's a city? Looks like New York City. Maybe that's a clue.
