To me, it doesn't matter how old Kurt Russell gets nobody but HIM should EVER play Snake (unless he's no longer around). They need to get off their butts, forget about a remake, and make the final movie, like you said, with Kurt Russell. And I'd be happy. If they ever decided to do the prequel, Escape from Cleveland, I could probably except someone else playing Snake (since he'd have to be really young), as long as he looked very similar to Kurt Russell.
