bungie specifically said this would be the last game of this story arc.
a story arc is a typical plotline, you know, introduction, rising action. climax, resolution.
there can easily be other games with master chief but it wouldn't be called halo because maybe at the end of halo 3, the halos are destroyed, or the flood are taken care of, whatever. and there can also be a prequel series of games of course.
