The Inside Bungie Blog (thanks Edge Online) outlines the developer's plans to attend the Penny Arcade Expo 2008 at the end of next month, encouraging fans to come by and check out some new Halo 3 multiplayer content. They also say that in spite of the failure to launch their big announcement suffered at E3 (story), they will not be making any big announcements at the show, though they do tease the fact that they are currently working on "three distinct projects…some familiar, some not. Some on a closer horizon, some quite far off." Word is:

For the record, we have no plans to make any big announcements or huge reveals at PAX this year. While we will have some Halo 3 multiplayer stuff for you to check out, this is not going to be the "big announcement" many of our fans are clamoring for. Rest assured that when the time is right, we will be making announcements and talking about the stuff we're currently working on. At the moment we do have three distinct projects underway within Bungie - some familiar, some not. Some on a closer horizon, some quite far off.
