Okay, so here are the MSEP/DEP rumors we have so far:
*Tinkerbell, though I wouldn't say it's a rumor becuase it's been confirmed. The only rumor surrounding this is whether it will replace the Blue Fairy leading the parade or not or if it's just going to be added somewhere into the parade.
*The classic awesometacular version of Baroque Hoedown might be replaced by the OK-tacular DreamLights redition.
* The Dumbo's Circus Units (all 6-9 of them) will be replaced by one little Snow White Unit that did in fact both run 13 years ago at the same time back at DL. WTF.
* All current units will be replaced with brand new ones.
