behind the scenes guest speculation

There have been a lot of talk about actors showing up but what about the behind the scenes people.
Celebration I had a pretty cool line up of behind the scenes people: Rick McCallum, Doun Chaing, Ben Burtt, John Knoll, Trisha Biggar and Ian McCaig. Also Terry Brooks was there to talk about the novelization. They were just as interesting to hear from as the actors and they were pretty cool. We even got our picture taken with Ben Burrt.
Any speculation about this types attending in Indy?

 

I agree, Oscar. Ben Burtt was one of the most interesting speakers I heard in Denver. He sounds like a great guy, and is more intricately involved with Star Wars than most fans realize, I think.

I'd like to see/hear some of the voice actors in Indianapolis. One of the coolest (although a little freaky!) moments on the TPM DVD Documentary was seeing the actor who provided Sebulba's voice. But guys like him the actor who did Watto's voice don't get as much recognition... so it would be good if they could appear at the Celebration.
