It's closer to eleven now that Baloo's been leaked.
As well, we know for certain that an unknown Marvel figure is packaged with New Cap for the playset since Ant-Man, Vision, and Black Panther are single releases. At this point it has to be Scarlet Witch, especially since JV said in a tweet late last year that all 3.0 playsets will be packaged with both a male and female character, ruling out Bucky. *EDIT* Welp, as of this afternoon, only New Cap comes with the playset. RIP the Scarlet Witch dream.
As far as the missing seven-or-so Star Wars figures? Anyone's guess. They said in an interview they're not doing droids, ruling out R2-D2, C-3PO, and BB-8, so my guess would be something like Grievous and Mace Windu for the prequels, Lando and Emperor Palpatine for the original trilogy, and...okay, The Force Awakens is a bit harder...Maz and Snoke? Either that or Phasma. And then Hera Syndulla to round out the Rebels cast.
As for the last eleven Disney Originals? We have confirmation there's another playset, and considering Star Wars is covered and Marvel only has one unrevealed character, it has to be Disney. Considering basically every playset since 2.0, and including one of 1.0's, has had at least five characters, I'd assume the same for this playset. As for what it could be, I see three possibilities:
A) A Through the Looking Glass playset with (sadly) live action Alice, Mad Hatter, Cheshire Cat, Queen of Hearts, and White Rabbit, as examples. This is due to the movie coming out soon.
B) A Muppets playset with Kermit, Ms. Piggy, Gonzo, Fozzie, and Animal. This is due to their recent TV show.
C) A Gravity Falls playset, to coincide with the finale. This would be harder to give five characters, but I could see Dipper, Mabel, Stan, Bill, and either Ford or Soos. Though realistically, I can't see more than four here.
Whichever two don't happen, the remaining get two figures (Alice and Hatter, Dipper and Mabel, Kermit and Piggy). That'd bring the total to nine out of the eleven, leaving two characters. I'm still certain of Kim Possible, so there's one more. That leaves one more unrelated figure. Based on what's been showing up the most on various official surveys, combined with the team's wish to add more female characters, I'd wager this one is Cruella de Vil. That'd round out the Disney section well for this game, I think.
