I'm headed to Austin in a few hours. The conference is Wednesday through Friday. If I get a chance to post another article in that time, I will. It's more likely, though, that I won't post another until the weekend.
Bear in mind that the AGC, if it's like last year's (ownership changed, so who knows?), isn't about showing off games, previews and interviews. It's more about developer strategies, design philosophies, marketing strategies, legal issues, market projection, and business-oriented stuff like that.
So don't expect much big news. The articles everyone writes afterward will probably be more about who they met, what they did, design discussions and rants, etc. More than anything else, the reason gamers should be interested is the insight AGC offers into where the industry as a whole is headed, what the developers and publishers hope to accomplish in the next year or two.
