It has been announced that in fall 2009 "Halo 3: Recon" will be released, which will be an expansion to halo 3, but will star a new character nobody has seen before.

But bungie made a mistake, and accidentally released some "Achievements" that might of originated from the expansion. They already and quickly corrected it though.

Only time will tell...
