I personally contacted a number of people from the original pinball 2000 team and invited them to either speak or get a personal demonstration of Nucore.  I got a couple of definates, a couple of that will try to make it, and one who was confirmed may not show if the Chicago Cubs end up playing a home game at night that thursday.  If they play a day game or an away game he'll come.  I can't fault him because I've been a Cubs fan since I was a kid =)

We'll also have RFM running on nucore on the exhibit hall all day Friday.  So everyone will get a chance to try it out and we'll get to do some serious pre-alpha testing ;-)
