Just my thoughts
Thanks for your thoughtful and constructive post.
I'm with you in hoping for JJP's long term success, and one way to facilitate that is for Jack to end a run with as few non-reuseable unique parts as he can. They can reuse screws, coils, and brackets in other games, but hundreds of Tortuga Tom sculpts, not so much.
The later, limited runs help turn those unique parts back into dollars for JJP to use for R&D and other things instead of spending more to warehouse the unobtanium parts of tomorrow. It's also a way to keep market mindshare in the long period between new pinball releases for everyone not named Stern.
