This is probably going to get locked very soon but I'll help out anyway.
Halo: Reach was announced for the first time at E3: 2009 with a short, seemingly-unassuming teaser trailer. Nobody knows much about it yet aside from what is in the trailer.
I suggest reading other posts here to get a better sense of what the community thinks about it. Also check out the Reach project page here on Bungie.net.
Aside from that, you just have to wait and see like the rest of us.
well thank you finally someone thats not a complete aesshole
