Quoted from Goronic:
TRON Pro: 618 Pinsiders Wish List (which is more than currently HAVE it in their collection)
TRON LE: 480 Pinsiders Wish List (which is more than owners - even more than Stern MADE)
Used Cost: (with some wiggle room)
TRON PRO average is 8K (~3K over NIB at release)
TRON LE average is 10-12K (~5K over NIB at release)
TRON Vault is by far the number 1 requested vault. This is rather obvious based on it showing up so often in threads (even this one). By using Pinside Search it appears to have the highest number of related posts - even more than LOTR.
Based on that info it would appear to be far more than 100 screaming pinball fans...
I would say hundreds (not 100) would likely buy a TRON vault.
Super interesting angle, yup, that's how the market felt around Tron, but you've done some digging and it is what it is, regardless the movie was a hit or not. There's definitely some huge interest in Tron because of the theme. The Shadow movie sucked eggs, but I wouldn't trade my Shadow away.. there's something about it, dunno, my gf and me clicked with it! And no, it's not because of Alec in the case of my gf! Lol
