This is crazy talk. This is a full on cash grab with Batman '66 and, because of Stern, JJP saw room to price up their game, so they're doing so.
These prices are unsustainable. I'm not priced out yet, but I'm done with NIB games. It no longer makes any rational sense to be paying these costs when there's no increase in game features and quality. Adding an LCD screen doesn't count as new features, because it's actually cheaper than a DMD display. Stern is raising margins as fast as they can, and it's greedy.
Do you think that their new investors really care about pinball? No. They just want to get their money back, turn a profit, and go find the next company to play with. When Stern (and JJP) took outside money, this was always going to be the end result. The investors will milk the customer base for as much as they can and move on.
There's no good reason for pinball to cost this much, especially from the two companies that build at the largest scale. It's all greed.
