Changing the show isnt a priority right now. SM always has hours long waits and is incredibly popular in its current format. The money and resources are going into FL to create something new. We as fans may not agree witht hat, as we walywas want everying pushed to 110%, but that isnt going to happen. All in all, I'd rather see the new FL and SM reopen without show changes, as oppsed to getting a DL style SM and no FL (or a hacked down FL).
Despite all of the money spent on DL SM, I actually prefer WDW SM in its current state. The shakiness and bumpiness is what its all about for me. If I want smooth, I can go for Everest or RnR. SM offers something very raw and different. I dont want everything to turn into a smooth ride with onboard audio.
