Yes. RSR/new PoTC would be Mega E tickets from this decade. Huge budgets, grandiose scale. Doesn't guarantee it will be the best ride ever, but they are spending like it.
B&TB is an 8 minute LPS ride from the Mystic Manor Imagineer. It carries a nearly 300 million USD budget just for the ride. RSR "apparently" was in the 200+ range. Still, budget comparables are always semi-useless. But they are spending about 1.8x the amount for this attraction versus Soaring that they are simultaneously building. Soaring WITH an actual nice facade I might add.
Compare the number of the ride vehicles (6) and number of guests per (10) versus the general scale of Mystic Manor (4) and (6)...
Trust me, no one is going to question that it's an E-ticket. Again, could be garbage... but it will still be an E.
