I think it's important that a clear scope is out lined in order to move forward. For example what are we looking to get out of having an expo? Is the expo just for new machines or do we want old machines as well? Are these then for sale? Will there be a comp?
Also how is this to be financed? Are commercial pinball suppliers invited to take part? Can it happen with out there investment.
 Of course opportunitys need to be explored and comic con has potential to be a great fit so great job Watto getting the ball rolling on that one .
