Halo 3 Goodies coming?

On the company's most recent Weekly Update, which is posted every Friday, community manager Frank O' Connor says the following: "A bunch of stuff is going down to celebrate the fifth anniversary of a little game we like to call Halo... Next year, Halo 3 will conclude the story arc begun all those years ago and next week, we'll take a long lingering look at the series to date. There will also be some pretty BIG surprises and maybe announcements. Who can say?"

New trailer perhaps, ingame footage? maps? Official release date?

I want to see the packaging design, i bet its going to be special this year after teasing us with a semi-nice metal tin for Halo 2.
