The coaster? Yes. The project? No. A coaster like this may have just gone from $10 million to $13 or $14 million to build. LSM launches are pricey although the plan all along may have been to have an LSM lift hill (like California Screamin'), not a chain lift. That would lead to a largely negligible price change on the coaster track. The theming, with the trenches, could have easily cost (WDI) a further $90 million to complete. They've probably cut that by something like 50%. What was a $100 million ride (I know that's absurd, and yet...) is probably now $60 million. Maybe they needed money for Guardians of the Terror.
As for the restroom building leaving, I assume that means a building over in the Woody's Round-Up village that was originally going to be something else will now be toilets. You need toilets in any land.
To answer a question from awhile back--the new launch should increase capacity. Coasters have block sections and I would assume a coaster train will need to have cleared the 2nd launch before a 2nd train can begin the 1st launch. Since the 2nd train will now reach top speed much more quickly, they have probably shortened the interval between trains departing by 5 or 10 seconds. That increases capacity by perhaps 15%.
