well I think you can certainly expect a lower budget on the last Episode given the social media reaction.
It looks like a 50/50 split so the budget will be aligned accordingly for losses.
More accurate research shows it’s nothing near 50/50, probably closer to 90/10 or 70/30 at the very least.
And when TLJ becomes the third highest grossing domestic release of all time, I’m sure any thought about decreasing the IX budget will disappear.
One can also factor in certain assets were already built for TFA and TLJ. (Sets props and costumes.) They aren’t going to let anything happen to the full size Falcon this time around when they can eventually put it on display in one of the parks.
