Good news from Bungie: The beta for Halo 3, previously thought to be limited to a minority of people who bought Crackdown, is actually going to be open to everyone... um, everyone who buys Crackdown, anyway.
The beta invites are included in the retail version of the game, and if you must mess around with pre-release Halo 3, you can just hop down to EB Games or whatever and buy your way in. Check the box to make sure it contains an invite, of course.
God bless America!
