So, if WW were to get a whole London section, with Diagon Alley, Leaky Cauldron, the MoM, possibly Platform 9 3/4, in addition to Hogsmeade, Hogwarts and the Forbidden Forest area (Hippogriff and DC), the park wouldn't feel dominated by HP?? It kind of seems like it would be to me. Like I said before, I am torn between being a huge Potter fan and saying, just take over the whole park, and being an IoA fan and not wanting the rest of the park to be forgotten.
But whatever. Like you said we are all just speculating. It's kind of fun, so if you or anyone else has an idea, where exactly would they even put Diagon Alley? It would be helpful if someone could reference a map, instead of just saying "the Arabian section".
