I agree with ICE seeing how fast LE's and GNR CE's sold they could do a really special pin in limited number for high price point and sell out. I don't know if the numbers would work without the pro/prem though, that's above my pay grade. They could do it until they have a dud and would probably be fine with the dud that everyone will be trying to buy years later.
I also agree with Aurich that it seems like they could dial down the amount of games designed per year and concentrate more on maybe even less title a year. That way you get more development time and you can keep the line going longer on one game at a time instead of swithcing back.
Something I have never seen explained is why can't they have different prices for different games? If the designer wants a couple extra coils it's priced more than a game that doesn't have as much. Why when they increase prices even older NIB games go up as well? I believe this is the only market where that happens that I can think of.
