Frankie mentioned that accountants were asking about travel budgets, since 343 is going to be doing a lot of touring around the world to promote Halo 4.
They mentioned marketing, like Slightly Live said, spinning up the marketing machine next year. Frankie said something like "some cool stuff if we can pull it off".
The multiplayer stuff went like this: The multiplayer team plays the game at 3 every afternoon, and they were playing and hooting at some new game or multiplayer feature the other day.
Frankie and the rest were talking about using some new weapon that sounded like a unicorn farting a rainbow. And yeah, that some of the weapons sound so good you want to use them because they sound good, not because they are the best weapon at the time.
