Updates have typically been patches or paid content adding to gameplay. What made you decide to offer this kind of content instead of something more traditional like maps or horse armor?

Well, we have already released 7 new multiplayer maps since Halo 3 has shipped – 6 of which were at least initially offered at a premium. The Heroic maps eventually became free while the Legendary map pack has had a price reduction but is still a premium download. Cold Storage was a special release for Bungie Day (7/7) and was free from the get-go. After careful consideration, we just couldn’t find a way to fit horse armor into the Halo universe. Perhaps next time.
