Whatever they want to make and then when they cut it off, they stop making it.
There is NO benefit to a business to make 250 of a LE so that the price can explode on the secondary market and it is worth 150% what people paid for it. The business that was selling it would rather make that money.
There is NO benefit to a business to make 1000 of an LE if the market only wants 250. It causes them to sit on unsold inventory and the price drops for everyone.
The best business plan is to make as close as possible to exactly what the market wants, and then that's it. Machines hold their value, not dropping like crazy (Transformers LE) or rising like made (Tron LE), which in turn gives collectors the sense that they are good to purchase more in the future. The business makes the most money possible.
I'm all for everyone making the most money on these. Personally, I like the JJP / Spooky model the best because I don't like there being two versions of what is more or less the same game to try to choose from. Having said that, I kind of feel like the Stern model gives us an extra couple machines a year, so that isn't bad either. More pinball = more better
