Louis Wu at HBO has put up a summary of links to interesting forum threads; many of them touch on issues I mentioned in the Annotated FAQ, which also included a short analysis of the Announcement Trailer. And before everybody goes nuts, I had to go ahead and do that without checking any of the forums first because I was already behind by 12 hours, so no, I didn't steal anyone else's speculations or screenshots. It's just a predictable coincidence that simultaneously a few hundred people focused on the same few things: pilotless Banshees, hidden scrambled images in Cortana's transmissions, Gravemind's voice, and the modified Assault Rifle.

Finn at the Halo Story Page has also pulled out some items of note, focusing on the structure in the trailer, the Master Chief's posh new gloves, and the weather in New Mombassa.
