The Weekly What's Update at Bungie.net this week, courtesy of Frankie, talks about the upcoming Team Hardcore playlist for serious, competetive players, including 10 maps and 10-11 gametypes. Check the update for a more complete list. Frankie also says that yes, Bungie knows that people still cheat, and they are still working on it.

As for surprise announcements:

Oh. Keep your eyes peeled next week for a surprising, cool, awesome Bungie-related announcement. No it is not Halo 3, nor is it the surprise revelation of our next project (whatever that may be) but it’s sweet. It’s something I’ve hinted at in the past. And you’ll probably like it. More than that I can’t say. Which even I know is aggravating. But it ain’t up to me. So just be patient.
