Does anyone else but me and my gf think theyre gonna make one sooner or later?

Hmm, I mean at the rate they're going nowadays, they're making movies for everything, so I wanna say yes. But I think it's kind of a touchy thing because even the movie-producers know they could easily make a lot of hardcore fans very angry. Hell may hath no fury like a woman's scorn, but it hath no power like that of an angry mob of gamers. So I think it's definitely a possibility but I'm not sure whether they actually will or not.

Didn't they promise one like with the first game??

Hmm you would think "worth the wait" or a "better hold off on it a bit" would be a better choice, but HALO is winding down in its story releases, so having a movie cover some part of the universe would be nice. There was an animated telling, but I am sure people would like to see a live-action version.
