Stern will continue to produce machines in thier "current lineup" for as long as demand is there (and the terms of the license allow it).
Stern Star Wars Pro and Premium (released 2017) in on the production schedule again towards the end of this year (2022) because of both demand and license agareements.
Stern Led Zepillin is currently "listed" on the production schedule, but there are no plans to make any in 2022. The license allows it to be built, but the demand is not there.
Newer games like Mandalorian, Godzilla, and Rush will be run a couple different times over the course of the year, but games like Jurassic Park, Avengers, and TMNT will only be ran once this year (and then, probably, again next year).
