I've been recently been rewatching some disney infinity video sand I came upon a few things.
1. If u watch the press video u see the whole presentation ending with the castle with some video footage of the game, and if you watch closely u will see Vanellope.
2. Also I have heard that zurg won't be a figure to play as but a villain that can be placed in the toy box.
3. Plus that skull like tower we always see, I've been told by some I know that it is part of the pirates Playset.
4. Lastly in the preview video of holly Shiftwell , shows Finn Mcmissle, he will be a mission giver and u can place him in the toy box.
