Halo 3 bacwards compatability

So i've heard rumors about halo 3 coming to xbox one around september 15, and if anyone knows anything leave a comment on this thread, have you guys heard of a final release date?
lol what do you mean " about two months ago,yeah" do u mean they gave us a release date two months ago? and when if so? 
No, I mean they announced it about two months ago, release date's TBA. (It is four enormous games at once.) I can only assume that they'll be ready when they show up on the store like they do the others. I doubt there will be a publicized release.
