the more I watch the ending video the more I'm convinced, there's no way he's dead. After being injected and shot a million thousand times by various weapons, he gets to sit in lava, for..a very long time. A ridiculous ammount of time, a rock dissolves in the lava faster then wesker seems to..Then, Rockets fly past his head into the lava behind him. I dunno, I don't think they'd put such emphasis on them missing if it wasn't important.
I agree. Additionally, I can't see Capcom killing Wesker off until the very last Resident Evil game. While I do think it would 'cheapen' the ending of RE 5 to bring Wesker back- I do agree that they kind of made a point of the rockets missing so we don't really know.
