"And it's taken me this long/ But baby I've figured you out"

We are hurdling towards the SERIES finale of LOST. Ahhhh... what will I do with myself when it ends? How will I waste hours sifting through message boards and comments for one theory that has a glimmer of being right (only to be dashed an episode or two later)? What will I talk about with my friends for hours on end? I don't even want to think about it.

But what I am thinking about is how is it going to end. Just so in the event that my far fetched guess is right, I am writing it here so I can accept all the glory. This is my non-definite ending theory. (Meaning if it isn't going to end with one side ultimately winning-- if good doesn't prevail):

Let's recall the conversation between Jacob and the MIB (are we ever going to learn his name!?!) during season 5 where Jacob says "It only ends once, everything else is just progress". I think that Jack is going to become the new Jacob and it is going to end after X number of years with Jack bringing a new batch of people to the island... perhaps by plane crash or a wayward boat, whatever. But maybe it will end with a new person opening their eye a la Jack in the pilot and it's going to start all over. And everything that we have seen, these past six seasons, has been progress. I'm not saying I like my theory, I just had the inspiration after last week's episode.

So that will mean Jack is the new Jacob and FLocke will remain as the MIB. I threw out this theory to my fellow LOST-obsessed friend TW and he said he thought maybe Sawyer would be the new MIB. I think this can also be a solid theory because Sawyer has always been the one so desperate to get home and he and Jack have always been against each other. Admit it, it makes a little bit of sense.

So that's what I think. Anyone else care to share their theories? Only 3.5 hours left. All I know is I'm not emotionally prepared for this.
