Really good interview! Best part was JV confirming more playsets to be announced which I'm really really surprised at! I completely believed we'd only be getting the 5 that have been announced but we're getting more?!
I think it could be either a Disney or Star Wars but not Marvel. Most likely Disney, hopefully not Pixar to make some people more happy. I remember in another interview when someone asked him why only Live Action and Pixar play sets for Disney and JV laughed and said "Stay tuned!". This will probably be what he meant!
Zootopia or a classic Disney film are most likely.
