It will keep going up in value. Everything Collectable always goes up in value.

Such a generalistic comment couldn't be further from reality.....

Collectable markets are full of hi's & lo's, collectors sell out, new collectors come along, markets get flooded, markets dry up, it's keeps oscillating, but it never constantly increases......NOTHING DOES !

I highly doubt pinballs will reach $100k or $1million in 50-100 years based on your comment   ;-)
