Halo 3’s announcement at E3 has been subject to much speculation, though it seems pretty likely, especially after hearing a few words from Bungie.

"As for our next project, it continues apace. Lots of progress in every department, from UI to Animation to Engineering and of course, all the way back to audio," Bungie revealed in their weekly update.

"There are things to see in every department, some rough and ready and some astonishingly smooth, polished and even playable.

"It's really making progress in an exciting and fascinating way. And I can't wait to share that with you properly. The level of secrecy is every bit as oppressive and confining for us as it is for you. Much, much bigger update next week. See you then!"

Sounds like something will happen very soon.
