The report from Jim Hill was a dark ride where guests would activate things using a wand, presumably similar to the Monster's Inc ride in Tokyo. I don't know if it would have used the same ride system (it's the same ride system as TSMM). The other component would have been a care of magical creatures petting zoo. It doesn't sound like the initial plan would have been anywhere near as expansive as Hogsmeade's Village, but I don't know for sure.
And you likely never will.
Because of ownership rights to the Potter IP, you aren't going to see it in the next coffee table book on all those amazing projects that WDI never follows through with (at least in the FL swamps).
I do have it on VERY good authority that Disney's pitch wasn't nearly as impressive as UNI's. ... But I am sure Disney could have done just as impressive work IF they wanted to. Thing is, though, Disney never really wants to.
So ... go make your ressies for your next three Pixie Dust hits and enjoy riding your MAGIC Bands!
