no, reach will probably not be the last one. i can see maybe one more coming after that. Why? because xbox 3 needs a halo, but also i like what they're doing here. reach is a very interesting chapter in the halo universe, and this gives me a very much like star wars feeling. i like what they're doing with odst too. the thing is, i am hoping for a fresh new graphics engine. back in 2007 the engine was pretty decent, showing some incredible lighting, textures and particles. sadly i think for 2010's standards, they do need a new engine, altough i do personally have to say this should've been announced next e3, because halo odst and halo wars is already a lot of games regarding the halo universe for a while.
