IMDB takes fan updates, so that's a grain of salt there. Last I've been hearing on Christopher Lambert's website is that he will the third film. And this has been going on since at least 2003. He only didn't do the second film because he didn't like the script and depsite what one thinks, every film he does is based on what he considers to be a strong script. Tha's why he's only done sequels to Highlander and waited so long to do the sequel to Fortress. As to Bridgette Wilson, I think it's been indicated that she wasn't going to be brought back, but that Sandra Hess would be used.
