Halo Reach was released on September 14th 2010.
This is a difficult question to answer, because Halo: Reach is coming out but Bungie is not sure to release it or not. But there will not be a game with the exact title Halo: 4. But there will be a Halo "4" but replace 4 with Reach.
Halo Wars is to be released January 21, 2009.
