I understand these points and readily admit that we're largely discussing impressions rather than anything approaching objective characteristics of the ride at this point. I would agree that they are emphasising more than anything the earnestness of their intentions with this redo and, to a lesser extent, trying to reassure fans of the original ride that it will still include animatronics and more generally be an attraction of the same standard.
Just logically, I think one of the problems the design team has to confront with this project is mapping an IP with a younger fan base onto one of the parks' premier thrill rides without excluding too many of those younger fans who would otherwise be excited about going on the new Tiana ride. I'm not sure many people would argue with the notion that if you were designing a PatF ride from scratch that you wouldn't put this level of thrill into it any more than you would with a Little Mermaid or Beauty & the Beast ride. This, to me, helps explain why there is so far no hint of peril or thrill involved in how they are describing it, and I would not be surprised if the final version tries to present the drop in as calming a way as possible.
As for the structure, I do think there is a clear effort to downplay the height of it that is perceptible in the concept art:

In the first version, you clearly see an effort to make the drop and the surroundings look as perilous as possible, including by drawing the eye upward to the peak of the dead tree to make the mountain seem taller. In the concept art, the mountain itself more or less disappears behind the trees, greenery, and water tower and the drop presents more as a waterfall in a generally tranquil setting. The eye is also naturally drawn to the water tower rather than the peak, at least in the concept art.
I'm sure a lot of this has to do with their unnecessary obsession with the need to explain a mountain in Louisiana, but I do also think the presentation of the drop changes significantly from ominous to tranquil.
