I wouldn’t exactly call five blockbusters for “passive”. I’d imagine they’ve made a ridiculous profit on it already, and I don’t see how a hiatus of a few years could damage them financially. After all SW, unlike Marvel, isn’t based off of comics so they have to treat the two differently. A film or two each year makes sense for comic book movies, but it would make sense to be a bit more cautious with SW. Plus I’m getting the impression that Lucasfilm has maintained a lot more creative control than what was initially assumed.
I wouldn’t be surprised if they just kept pumping out a new SW film every year, but I think they know their audience well enough to know that they have to thread more carefully with SW than with Marvel. Plus I imagine the merchandising alone would make SW plenty profitable even if they stopped making movies for a few years.
At the very least, they might have a relatively “long” hiatus on making saga films after E.p IX, and focus more on the anthologies. There’s still those rumours about a live action TV show, so that could replace the films for some years as well. (RO was after all originally pitched as a TV series.)
