I think this could be good in terms of getting more people involved and creating larger market. This helps the viability of existing companies and may attract new ones or at least increase production or titles at existing ones (assume this show becomes a hit).
Pinball is not focused on buying and selling and making money. Market will dictate price conditions. I pinball because it's fun, has great community, and I enjoy the restoration and collection aspects of it. If the prices double in the next year, that just means I may collect less but it doesn't change how I feel. It will mean my collection is worth twice as much as well, so that doesn't hurt.
I say the more people, the better!
