Major Nelson dropped some cool stats about the Halo 3 beta that just ended.

Microsoft and Bungie collected endless amounts of data to help tweak the game, but here’s some interesting stats about how many people actually played:

There were around 820,000 unique participants with more than 12 million hours of online gameplay. That’s a LOT for a beta! Also, the game racked up 350 Terabytes of data downloaded from the Live servers. That’s gotta a fun bandwidth bill.

This is definitely an indication of how many units Halo 3 is going to sell… could honestly put the console war out of reach for Sony and Nintendo.
