First and foremost, I think everyone of the major characters is going to die in the Island reality, I think they will be given a choice by Locke or Jacob where they can view the life that happened with the Island and without the Island and they have to choose. If they choose the Island their counterpart dies horribly, if they choose the alternate life then they die horribly on the Island.

I bet the same is going to happen with Locke as well. When he talks about leaving the Island they won't be physically leaving the Island.

I've noticed that as the characters have been redeemed on the Island they've been redeemed in alternate life. Thats why Sawyers life is still a mess off Island, and Syaid's life is a mess off of the Island.

But I think they're all going to have to make the same choice.

And thats why the Island is so desired by the Bens and the Jacobs and the Widemores, because it will allow them to choose their reality.
