Halo - Coming February 9th?

I've been hearing some reports that if you beat "Halo 2" on Legendary Difficulty you'll get an odd message in the credits, "Coming Februrary 9th". This has led to speculation that "Halo 3" may be released on that date in 2006, that Bungie may announce "Halo 3" on that date in 2005, or that perhaps some downloadable content will be released on February 9th. My guess, and that's what it is, a guess, is that new content will be available only for those who have beat the game on Legendary, thus rewarding those who are the true "Halo 2" elite.

In other "Halo 2" news, CNet News is reporting that "Halo 2" is being used to sniff out modded Xboxes.
