I wouldn't base a lot on a test screening rating. All kinds of factors at work there, from almost certainly not being the final version to most people not knowing how to watch a not-totally-finished movie.
That said, I have more confidence in this world wide than domestic.
There's no chance of a Star Wars movie hiatus.
Here's a big reason why-

Gotta keep it alive and in front of people.
I expect IX to go down, at least overseas. That's mostly because os seems to have lost interest in the franchise and I lack the imagination to see how they can earn a significant part of that back in one film.
Domestic it could hold or increase, if it's done well.
For the record, I think it's pointless for people not directly involved in a film's finances to speculate about its profitability. You don't know, you won't know, and you can't know.
You can guess if it makes you happy, and sometimes it makes me happy. But I'm not silly enough to think it has much to do with how it actually stands.
Sure, I believe their profitability analyses to be simplistic and often wrong too.
They just print them because people like to read them. They don't have much to do with reality.
It's not. Some geniuses are boycotting a movie they'd almost certainly enjoy to make a point about the last one.
How they imagine this is going to get them results they want is beyond me.
My secret personal take - Rian Johnson fell in with the film critic twitter crowd years ago and made a film to please his social circle.
That's cool and all, but please a few dozen people isn't the way to make blockbusters.
MI:whatevernumber it is could break 200.
I don't believe in A Star Is Born, but a lot of people seem to somehow.
Fantastic Beasts 2, obv.
But yeah, it does look skimpy outside BV releases.
