I heard from a trusted source that the current model under discussion is a plan to expand WWOHP out the back of the current IOA and all the way over to Universal Orlando, with a Hogwarts Express running between "Diagon Alley" at USO and Hogsmeade station. I hope it's right; it would be pretty awesome, especially if they include a Knockturn Alley at USO. I've no idea what attractions/rides are planned other than the express, though. But I hope it'll be MUCH bigger with many more attractions - Universal is doing so very well thanks to Harry, I'd be shocked if they didn't really take it to the next level. Especially to keep in sharp competition now that Disney is bringing an "Avatar' land to Animal Kingdom... Hurrah for healthy competition if we all benefit with new HP stuff, right?
