Many Halo fans seem rather pissed off that Halo 3 actually sports last-gen graphics, garbled voices, and a terribly bad soundtrack, with no replay value what-so-ever. I haven't tried the game itself but do remember watching gameplay video clips of it on Tech TV and thought "These graphics aren't any better than halo 2 for the first xbox." - Some people say the graphics are actually worse.

Is the Halo series finally finished?

I think the series will be milked dry for every last penny like FF VII
