So, WDW doesn't have a full roll out yet. They do have them in: Let The Magic Begin, MRFF, Most Merriest and the Christmastime Parade.
As for TDR: I'll believe it when I see it. It took them til the early 90's to get rid of the 80's looks, and since they never took up the DWAM ones, who knows if they even like these? I do know that the 90's look is in the concept art for TDR's spring events this year. So maybe if they have to have them, it'll start with Dreamlights' 2017 renewal or TDR's 35th next year?
Also, don't flame me for this. Does Disney really need these?!?!?!?!?!?!?! I grew up with the 90's look and I think they're in awesome shape and are still relevant. I guess I can see the 80's to 90's change since Mickey's voice changed around 1990. But the new ones ..I think they look weird and are not needed!
