That would be really cool if they finally brought the pre-parades back. Like the ones they did for Enchanted and the Chronicles of Narnia: Prince Caspian before Walt Disney's Parade of Dreams when those movies came out. Even the one for UP before the Pixar Play Parade. I'd love see that kind of stuff at the park again.
I used to really enjoy the pre-parades before PoD too! It would be nice to see one again. It was something they could meet demand for the newest thing with and always change often enough to feel fresh. I must have watched PoD dozens of times over the run and was still always interested to see the newest pre-parades.

Looks like as long as they can hire enough people in time, we can expect an Anna/Elsa Frozen Pre-Parade for the summer. At least guests won't have to wait 4+ hours to catch a glimpse anymore.
Can I ask where you heard this? I saw something on somebody linked to a random twitter post about it, but I didn't know to trust a random comment like that. It would be a very smart move on Disney's part to do something like this. The Frozen craziness at Rope Drop is a little nuts IMO.
