Looks like Microsoft added a few more keynoters to PDC 2008:

Today, Microsoft announced that architects Don Box and Chris Anderson were both added to the lineup for the Microsoft Professional Developers Conference (PDC) as the newest keynoters. Don and Chris will present an energetic and exiting presentation as they “live code” at the event in front of the house of attendees.

Microsoft has also extended the Early Bird registration deadline for general attendees to give those interested in attending more time to register for the event at the discounted price. The PDC is set for October 27-30, 2008 at the Los Angeles Convention Center. Early Bird registration will now close on September 8th.

I know that Ray Ozzie and Rick Rashid were previously announced as keynoters. But I'm not sure if there are others.

Either way, see you in LA.
