Even if this Universal does "out-AA Disney", both Universal and Disney are improving upon their weaknesses with these new attractions. Hagrid will give them a much more themed environment and have pretty much NO SCREENS - something that will be refreshing for Universal. On the Disney side of things, many of their rides actually do have AAs or are reliant on a more physical environment as it is (and both Star Wars rides seem to be very immersive in the queue and ride portions for the most part with a themed practical environment). They are also giving Disney some "Universal rides", as I think of them, since Disney has lagged so far behind Uni on these types of rides.
For both Universal and Disney, these attractions will be big wins and improve weaknesses as I stated.
