Well the announcement is in... Halo 2 is completed. I soooooooooo can't wait for November 9th; I know what I'll be doing between that Tuesday and the following Monday ;-)
In addition, I came across some other goodies concerning the Halo 2 (and Xbox Live in general) front.
One is that Plantronics is going to be making a Halo 2 branded Xbox Live headset. Plantronics makes some nice phone headsets, so this might actually be very promising. The ones I've used thusfar have not impressed me; it seems the “free” one that comes with Xbox Live works the best.
For your desktop, you remember that annoying talking wizard or jenie? Well, now you can have Master Chief yacking at ya! You can find more information here.
