LOST Finale Predictions!

Okay so here we are. The finale! I am posting these spoiler free, total speculative predictions based on the information the show has provided for 4 seasons. My two predictions are as follows.

Who is in the coffin.
Jon Locke 99% Sure
Desmond Hume 1% slight possibility

Locke will be meeting his demise because...
-In season 2 Locke and helen discuss obituaries. She tells him it's the only time people will always say something nice about you. (jack carries an obit during Through the looking glass.)
-ben Warns Locke in cabin fever that there are consequences to being chosen
-Jack is torn by the death of the person in the coffin, and also feels regret towards leaving the island. Locke wanted them to stay and jack wouldn't listen. He has been working as jacks spiritual guide and rival since the episode white rabbit where the theme of science and faith come into play.
-Locke has work to do, as said by taller ghost walt. Like micheal he can not die until he fulfills his destiny. Which may happen with saving the island.
-Locke with the exception of ben would cause the most animosity between himself and the Oceanic six.
-He with the exception of desmond, is the only main player whose future we don't yet know.

Demond may be dead because
-The writers introduced a plot device in the form of a charles dickens book which will be the last thing he reads before he dies. Desmond has yet to read this, and as said to him the only way that can work is if he knows when that is going to happen. Allowing the viewers to know that date would work in the same vein and set up season four.
-The animosity he may have could be that he did not help ferry the survivors to the boat, although it is more likely that he is now working for widmore. Which would be a big problem for the oceanic six. He may be working to hide and keep penelope alive which would result in him turning on Sayid whom he has been working with as of late in a sort of futuristic parallel of how things have changed.
-The resulting conflict of Bens war with widmore may take desmonds life while trying to protect Penny.

Who will die during the escape
Micheal Dawson 90% Sure
Jin Kwon 9% Chance
Juliette Burke 1% possibility

Micheal is going to die because...
It has been alluded to since episode 8 when he said he came here to die.
It is the only way to redeem himself.
He will never be forgiven by the survivors

Jin might die..
-To add emotional impact on micheals death. Like anna lucia, her death was not a big problem for viewers, since she killed shannon, so libby was also axed to make the impact more emotional.
-Michelas similar crime may call for a similar consequence of jins death by exploding freighter as well as some red shirts.
-It is more likely Jin will not die but it will be ambiguous as to whether he survivors or not until next season.

Juliette could be killed since..
-Her story is more done than others
-Without ben or his outside world others in play her on island missions are done
-Unlike other people, she could return home without a care and go back to being happy
-I just have a funny feeling this might happen


Oh and as for the finale twist. I have no idea what so ever.
