There is also the possibility this could be for a future expansion. The TV show is due to run for 7 seasons so plenty of time to develop new attractions.and locations.
I'm still hoping for something Lord of The Rings but I'd take Harry Potter over Shrek any day of the week
I'm hoping it's for an expansion also. It does feel like it's coming very late in the process as an opening day land. That and I want LOTR so much more, it's a completely unique Theme Park IP and has the same name brand recognition that HP has.
Also, if you plunk down HP on the concept art that released you could basically call the Park a Universal Beijing clone.
