Every time we get a new character, the first thing we do is play with them under my account so their statue ends up in the Hall of Heroes. So while exploring things the last time we got a new character, I noticed the following but forgot to take pictures and discuss it then. But now that we have Mickey I remembered it and here we are.
The first picture here is a terrace area behind the HOH. There are six empty pedestals. Now the front two don't look like much but the middle two look very similar to those that the crystal characters have been placed. Could these be future characters? Could they be future special characters like the crystal ones?
Now one thing we have noticed about the Crystal area is the spacing. I don't have the full area in the picture but it will serve for what is needed. As you can see, there are two empty spaces next to crystal Lone Ranger. These spots do not have pedestals in them either. Now if the crystal characters we are aware of were going to be the only crystal characters released, one would believe they would create this area to be equal. As you may notice when you play (as you can't tell in this picture), there is one pedestal to the left of Lightning McQueen. That pedestal is for Buzz and the empty pedestal you see in the picture i believe is for Crystal Mickey. To the left of that pedestal for Buzz is one open area unlike next to Lone Ranger where there are two.
