Anyone know who is going to be at the autograph  booth in the dealer's hall this year?

No Media Guests of Honor have been announced for this year so far. There may not be any this year (just like last year).

However, if you click on the Experience menu above and select Guests of Honor, you can see other luminaries who will be present.

I heard austicke will be signing autographs and posing for pictures on Saturday.

Yeah, I'm hoping 2017 will be the first year someone shows up for my autograph line. The 16th time is the charm!
