Well, I sent in my name to go on the list, fingers crossed, just a waiting game now. Marc from BigBangBarStuff was helpful and did say that the BBB can be worth a mint. This is what he wrote in a recent email -
"The BBB project is long done and any machines available are in collector's hands. There are some NIB BBBs out there, but I hear they are going for over $20,000 USD. I think used ones go for $8-12k. If you are interested in a new one, I know of a guy that has a NIB. I think he rejected an offer over $20k already, so I think it would take $25-30K to get him to let it go. I don't think he wants to sell it, but has not set it up yet..."
So with that said I think the Kingpin should at least holds it value and from reports sounds like a awesome game.
