Computer and Video Games managed to nab studio head Pete Parsons at Bungie to interrogate him about Halo 2. However, Parsons was on top of his game, and didn't slip once; about the release date there's nothing more than "when it's done", and about the game itself it sticks pretty close to the line that Halo was great and Halo 2 is just making the whole experience even better. (Not that this isn't true... but he liked The Library? Hmm.) Anyway, there are a few items:

• Halo 2 on PC. Parsons was noncommital, not saying yes or no to a port.
• Halo 3. Parsosn was noncommital, saying Bungie has lots of stories and loves Halo. Again, neither confirmed nor ruled out.
• Downloadable content. "Cool", but neither confirmed nor denied. (Seeing a pattern?)
• A prophet has been seen during in-game footage. This may be the video shown at X03 and mentioned by SketchFactor over at Bungie.net.

There's not a lot of new information here-- something that Parsons himself admits. But if you're interested in reading between the lines, take a look. Thanks to Louis Wu at HBO.
