I voted No because in the comics he was an important role in the phoenix saga, but this being a movie, I'm going to say he will die, and just the way the AICN script review said he will. There's alot of evidence right now that is pointing to him being killed at the lake, pics, and trailers. I remember reading an interview, that when mardsen signed on with superman, that the writters for x-men were considering writing his character out of the film, but then mardsen said he wanted to come back to reprise his role of cyclops, I think he siad he would even do it for free. I beleieve at first, they thought mardsen wasn't going to return, and also Halle said she wanted a bigger part, so they were going to have him replaced by another actor, then have him killed off in the beginning, and have storm take over his role as the leader. but then mardsen decided to return, but due to his limited time, they decided to keep the cyclops death included in the movie, and too keep Halle happy. So if this does happen, and your unhappy, you can blame part of it on Halle.
If I had it my way, when Jean takes of his glasses at the lake, he ends up shooting her, knocking her back and thinking that he killed her, but then she arises, not as jean, but as the pheonix, and throws scott into the rocks behind him, she then turns back into jean, and after seeing scott laying still on the ground, freaks out and faints or something. Proffesor X, senses that Jean is alive, tells logan and storm to get to the lake. They arive there to find Scott and Jean lying on the beach (maybe jeans powers are going haywire, and a bunch of rocks and crap are floating in midair (scotts glasses too)). They take them both back to the mansion, Jean awakens to see Scott in a bed next to here, bairly klinging to life. Logan tells her that scott looks in bad shape and probably won't survive. Jean freaks out, tells logan that she did that to scott, but it really wasn't her, that a dark power is inside of her that can controll her when it wants did it, she then tells logan to kill her so she can't hurt anymore people. yada yada, logan can't, then all a sudden, the phoenix arises, attacks a few people, then leaves the mansion, then later joins with magneto.. fast forward to the end, the pheonix is attacking everyone, including the brotherhood, maybe rogue or someone goes to the mansion, and descovers the scott is awake, they tell him whats going on. He arrives at the battle scene, and tries talking to Jean, telling her he loves her, and to fight the pheonix, Jean fights the pheonix, and wins temporarly, she meets scott, and tells him that she can't hold off the pheonix forever, that the pheonix will gain controll again, she tells scott to kill her, he refuses, but understands that she must die in order to save the world, he tells her that he can't not live without her, and that he will go with her, Jean them summons the strength of the pheonix, and destroys both her and scott together. and that's what the memorial at the end could be, a memorial to Scott and Jean.
I hope that's what happens, but who knows, I know Singer would have never killed off scott in the beginning, I guess we only can wait to the first reviews of the test sreenings, to know forsure what happens.
