Ben is off the island, so is Sayed (as we see in The Economist).
Edit: To be more clear. I don't think the island is going to move right away. I think the island will be moved once the O6 (including Sayed) get off the island. Once they are rescued, the island will get moved (while Ben and the rest of the Oceanic survivors are still on it). Then eventually Ben will leave the island w/ no way to know where it actually moved to.
Plus, I forget the episode name, but the one episode where Ben kind of wakes up in the middle of the Saraha Desert. People are under the assumption he may have "teleported" there, which is why he woke up a bit disoriented and not knowing where or WHEN he was (remember he asked the girl at the hotel the date/year).
So my theory is that the island moved and Ben had to make a hasty escape, somehow teleported and time hopped into the future, back to the "real world".
