Considering we all know Disney wants this a equivilant to Potter, we have to judge it as such..
We all know Disney wants this an equivalent to Potter? We all know that? How?
I think it serves a massively different purpose than hogsmeade did at IoA as well as a different purpose than diagon did at USF.
So Disney needs Avatar to essentially pull its entire resort out of terrible attendance and profits?
So Disney needs Avatar to sell park hoppers and merchandise/drinks/wand equivalents?
Should they have picked Avatar? Debatable
Should they have spent $1B? Nope
Is this attempting to be a Potter equivalent? Definitely not.

All of this wasn't done to combat Potter. And it wasn't all done to address Avatar crowds. It was done to make a more complete park. With longer stays for park goers and to take some pressure off MK with DHS' hell. I think they'll be successful here.
The Potter comparisons aren't needed outside of comparing immersiveness because they serve two entirely different purposes.
