Oceanic Six

I cannot claim authorship of this idea, but thought it was worth sharing. We're going on this assumption six people get off the island in the future due to Hurley's reference to the Oceanic Six. But I don't think only six people get off the island, and Kate is not one of the Oceanic Six. Consider - she's wanted for murder, when she and some other Losties were looking at getting off using Michael's raft she pocketed a dead woman's ID. Yet when we see her in the future, she's not behind bars. Leading me to believe that while a group got off the island and the became minicelebrities for a short time because of their ordeal, Kate was not one of them. Raising the interesting notion that more people - maybe everyone? - got off the island. And maybe Jack and Hurley's reasons for wanting to go back have nothing to do with leaving people behind. Or at the very least, more than six folks got off the island. In which case, who are those six? Jack and Hurley are confirmed. I'm going to put Kate in the Non Oceanic Six pile. Jin and Sun? Claire and baby? Ben?
