Along with the announcement of Halo: Anniversary came a teaser from Microsoft and 343i that answered a question many fans already knew the answer to: Halo 4 is on its way!

While no details were released about the game that will be coming in Fall of 2012, a short CG trailer was shown teasing all sorts of different aspects and goodies we may be seeing in the next installment made popular by Bungie (zero-g combat? Jet packs? Weapon attachments?).

Check out the trailer below and share your thoughts and theories in the comments!
