As has been said by many others Stern make great $5k pins in their pro models, really no one else can touch them in this department. However this does not always translate to the premium or LE models.
I think what's really going to hurt Stern is when collectors start loosing significant money on the resale of premium and Le models. Even for people with means pinball as a hobby has been a relatively cheap investment based on the ability to recoup most if not all of your money when you come to resale, hell occasionally you might even make a profit. This scenario took almost all the risk out of buying a new Stern Le, even if you where not wealthy you could take the plunge knowing if the game did not click you could bail with little to no loss. To me this is the one point that has separated Stern from say JJP recently, with a JJP game you know you going to loose a significant percentage of the value as soon as you open the box, as Jack has never truly limited his runs. However for most buyers they don't care as they not buying the game to flip and have the means to absorb the loss. If Stern has a run of releases where Le and even premium buyers are loosing thousands when they resell, then it will impact the desire of their product. WWE lost money GOT Le buyers probably break even GB slight profit Batman Le (not super) break even maybe even slight profit if code eventuates, Aerosmith Le probably slight loss , Starwars Le probably loss. If Sterns next game can deliver a level of demand where LEs once again demand a premium in resale then all will be forgotten regardless of the feature matrix. If they have another couple of tiles in a row where the Le loose significant money on resale then they are in the shit with this market. All the above is true for the premium buyers as well. If guardians or iron maiden or what evers next knocks it out of the park everyone will be back on the Stern train, if the next couple of titles drop the ball.... then yes Sterns Le and to a lesser extant premium model is in real trouble. Still show me a better bang for the buck NIB pinball the the majority of new stern pros??
