The point is, Rand will in some way survive the Last Battle. Like you say, the fact that virtually everyone is sure he's going to die pretty much guarantees that. And there are plenty of possibilities for ways it could happen.
So I'd say that the big 3 are out, as well as Rand's 3 wonder girls, Nynaeve, and Tuon. Good possibilities for death are, in my opinion: Lan (He's pretty much screwed if I'm right), Egwene, Moiraine (after all, she's already been dead for 6 books), Virtually any of the other Aes Sedai and Asha'man, Bashere (has to die for Perrin to get Broken Crown, same goes for Tenobia), Gawyn (but only if Egwene doesn't die. If she dies, he'll survive so Jordan can show us Gawyn's reaction), Virtually all of the Aiel Clan chiefs, a couple of Kings/Queens (like Alliandre and perhaps whoever it is that's running Arad Doman these days aside from Graendal), and (just a guess) Narishma (He's toast. Doesn't stand a chance. He's going to be running around close to Rand and using Callandor. Doesn't sound like the best option to stay alive....).
Other characters who I would guess are safe include Logain (his whole glory thing), Faile (Perrin doesn't get the Broken Crown without her... I think), Galad, Berelain, That one guy whose name escapes me who Rand made King of Tear, and Morgase.
Now this is all based off of what I want to happen / my general hunches. There are only a few that are based in fact. For instance, while I really want to see Egwene die, and it's possible for it to happen (and would be a great scene too), there's absolutely no proof that it will. I don't think that there's any viewings of her beyond the last battle, though, so she probably could.
One of the more interesting ideas I've seen is that Graendal, in her attempts to emotionally hurt Rand, tries to attack Min. She can't kill her (as per various viewings and prophecies), but she could seriously injure and/or maim her. That would really freak Rand out. I almost hope it happens. It could definitely spark a moment like the one on the cover of TGS (though this one would actually be cool, as opposed to cheesy).
Wow, there are way too many parentheses in that post. Oh well. You all love them!
