Louis Wu at HBO has posted a notice that there's an interview with Bungie Community Guy Matt Soell at HomeLAN. Among the highlights, he confirms that there are some unannounced surprise foes in Halo, aside from the Covenant Elites, Grunts, Jackals and Hunters we've all seen, and that adding online play to Halo would be more than a simple upgrade. He was also asked about what the experience of developing on the Xbox was like for Bungie:

Console development was something we've tried to get into as early as 1995, so obviously we're thrilled that we've finally done it. Learning the ins and outs of a system that wasn't even finished when we started developing for it presented its own challenges, but the developers didn't complain too much.

Soell also talks a bit about Halo's AI, level terrain, and future projects for Bungie.
