Not to put words into their mouth, but I think, people are on board for BHZA as an example because it is so limited, as in if you want it, order it. There will 3x as many Tron LE for example as BHZA. So people say will if Tron LE is worth $9k when there is also 900 regular Trons as well. It may be worth a chance on a limited edition. 10x as many Tron pins out there, easy to pick one up on the open market, with 124 total BHZA it may be harder to find after the fact.
Now if jpop said we are just going to make as many BHZA as we can sell. Likely a lot of people would have just wait and see and pick one up later.
I think it's remarkable that JJP was able to presell 1000 WoZ LE pinballs. Don't think that is any easy task.
Part of the reason I'm getting Predator, is because it is limited. I could just get a LOTR or SM for the same price and know what I have and resale etc. but the Predator is a chance it may not be great. So at least it will have rarity. So likely it will hold some value even if it's not as good as say SM. I know I can pick up a SM anytime I want since there are thousands made, if on the other hand it turns out Predator is better than SM for example, how likely will it be up for sale? Not as likely.
