Great that you can make this. I hope to meet you there!
As a staffer, I can let you know that a full lineup of speakers/seminars is definitely planned. Most will be on Saturday with some possible spill over to Sunday.
A co-staffer is working on finalizing the actual schedule, but I'm authorized to leak out a little information now

:
1. Crazy Otto will be in attendance! One of the original programmers (Steve Golson) of the "Crazy Otto" modification to Pac Man that eventually came to be Ms. PacMan will on hand to give what should be a very interesting talk on how Mr. Otto came to be. He will also have the original board set on hand with the original Crazy Otto modification that will be set up in a PacMan cabinet for all to play. He will also have a never-before-seen version of Super Missile Attack (he was also the programmer for SMA) set up in a Missile Command cabinet, and some other surprises we're told

.
2. Gary Stern (Stern pinball) will on hand to talk about his pinball ventures, trials, and tribulations.
3. Walter Day (Twin Galaxies) is set to pay us a visit with news from the Twin Galaxies front.
4. A panel of pinball luminaries is set to discuss upcoming innovations in the world of pinball...where the industry will/could go from here, what innovations will/might be in the works, etc., etc., to keep pinball alive and strong into the next century.
5. Richie Knuckles Pole Position contest.
6. Pinball tournaments (of course!)
7. Raffle prizes (a new Stern AC/DC pinball will be the grand prize!)
8. Return of the classic arcade-themed bands. We're still working on the actual lineup for these, but I'm told the music will be happening again!
9. Not sure which ones, but you can bet some of the old Atari folks will be roaming around.
Other surprises are being worked on, too, that I can't yet mention...one in particular should be quite interesting if it comes to pass. And I'll leave it at that...
See y'all at the show!
