Heres the thing, its not like Universals getting rid of practical elements in their parks completely. I mean hell; Nintendo is rumored to be mostly screen-less, Kong is mixing the two together; and for SLOP (Not saying if its either USH or UO), its seeming like a practical addition more akin to Poohs Hunny Hunt from Tokyo.
There needs to be equivalent exchange, and as much as I hate to say it; if you were to tell me that Fast and Furious would incorporate a mix of practical effects (Robotics/Wind/fire/E.T.C.) and the screen based elements of the 360, and Musion; sign me up. As long as they would not have the screen based element as a priority; I think that it wouldn't be much of a thing to whine about.
