Let's hope they do! I'd be first in line. It's an incredible deal if you don't mind the choices right now.
I'm just glad Universal fixed one of their biggest weaknesses and did so in a spectacular way. It removed quite possibly the "worst" (or at least the one most people avoided) counter service and replaced it with a whole bunch of incredible options that just so happen to perfectly tie in with the most popular television show of a generation. On top of that, the entire area is greatly themed (and will only get better once lagoon side done).
I'm looking forward to seeing how Duff Beer and Flaming Moes sales go. Butterbeer is like printing money, so much so that Disney just ripped it off thinking their guests would drink the copycat versions the same way. Didn't happen. Whether it's Butterbeer being better "tasting" or the fact that it has an actual connection to the Harry Potter property, nothing has approached it since it came out 3 years ago. Now here come two more drinks that many guests have dreamed/thought/hoped they would one day be able to try, and from all accounts they deliver. AND Flaming Moes has a unique concept that - like Butterbeer's foam head - is sure to be ripped off in the near future. If these two drinks (along with the food) bring in Potter type $$$ in sales, who knows what kind of things Universal will be able to do in the future.
