I'm not sure if this has been theorized before, so apologies if I'm repeating someone else, but it just occured to me that the island's unpredictable move is probably only unpredictable to the people on it/trying to find it. Remember, Ben said it was dangerous and unpredictable - but Ben never tells the complete truth - and maybe it was only dangerous and unpredictable to him. Most likely it has been moved before (Black Rock in the middle of the ocean?) without catastrophic results. So maybe the island knew EXACTLY what it was doing the entire time.
And because even without spoilers we know this season is all about DHARMA, then perhaps the island sent it back in time so Locke and/or Sawyer etc. can change the past. This time, maybe DHARMA is meant to succeed. Maybe things have become so out of control that the island wants to hit the reset button on all of Ben's time as leader, and who knows - despite the paradox - maybe if DHARMA is saved, 815 never comes to the island. I wouldn't be surprised, actually, given the concept of course correction, if this is how the series ends over the next two seasons:
1. The island goes back in time and the 06 they save DHARMA after a climatic battle with the Hostiles. Maybe even Widmore retains control instead of Ben. Maybe Widmore kills Locke.
2. Because of this, Desmond never loses faith, and never crashes the flight 815.
3. Course correction: there is a terrible rumbling in the sky during Jack and Juliet's book club meeting and they run out of the house to see 815 crashing for some other reason, unrelated to Desmond - no way yet to guess what that could be but I bet it has something to do with Ben if he's still alive at that point. Obviously the original people who survived won't be on the plane. And the entire show ends with Jack directing Sawyer and ... Frogurt? ... to go find the camps and make lists. They must know who's good and who's not. THe island is under assault from Ben's people and they must protect it.
Close with someone else's eye opening in the woods and a spirit of Christian Shephard saying "Go find my son."
The idea here is that it's all cyclical, and no matter the will and power of the island, human greed will always overcome good intentions. Jack will eventually be corrupted. Ben will eventually hurt the island in a desperate attempt to return. And it all begins all over again.
Of course this doesn't cover Rousseau (strongly think "they got sick" means time-travel sickness), Jacob (who the hell knows) or the smoke monster (really bad boar meat gas?), but it's more of a high-level overview and a prediction for the last scenes in the show, which Darlton has repeatedly said they've known since the beginning without specific details - and to me, this is one of the overarching themes that they could have thought of well ahead of time. They even foreshadowed it last season, for example, with the science team landing and Jack/Kate/Sayid/Juliet acting as the others from the Dan/Miles perspective. So that's what I think they knew from the beginning - that the leader of the 815ers (whoever it turned out to be after writing a few seasons) would one day become leader of the "Others" and watch his flight crash again with new people on it. Leaving them to make lists, lie and manipulate, and protect DHARMA and the island.
