There is no release date given for Halo Reach but it probably will come out in September.
No as of now the release date is September 1 but things can change.
March 2011
the release date has not been confirmed but it is a world wide release
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.
the same date the game comes out 14th of September
