Shacknews asks Frankie how it feels at Bungie now that Halo 3 is all finished. They also get to cover a few other bases: such as baseball in Forge:

Shack: How long do you think it will take before you start seeing things made with Forge and the gametype editor that you had never planned for or anticipated?

Frank O'Connor: Specifically about 23 hours ago--when those guys made [a] baseball [gametype] with rockets and gravity hammers--and that was their first pass at something!--and they even got bases in, we said, "Okay, all bets are off." We had no idea.

Also a few notes about DOA and Halo Wars.
