Here's what I CAN say. Animation Series #1 WILL have 9" figures, and while I haven't heard specifics about Villains Series #1, do remember that there was a teased Chernabog image posted on the website earlier this year. My guess is that we will see Jafar, Hades, Maleficent, etc. as 9" figures.
Simba is the topper, and Dumbo is in Park #7 last I saw. The Chaser has been chosen, is pretty obscure and not a design we've seen before.
