Might just be wishful thinking here, but toward the end of the video where buzz says "let's hope they come in peace", there's a flash frame that includes Minnie and Mickey alongside other older characters.
In the foreground is Miss Piggy and Animal from 20, and in the background is the Cheshire Cat.
Given Disney's re-launch of the muppets, and 2016 bringing Alice back to theatres, it seems like a big hint to me.
Of course, they could just be teasing - who knows?
Thought it was interesting enough though...
Also, I noticed today most of the figures on the survey that was published have been announced, with the exception of a few. Notably, R2D2 and Boba Fett are the only Star Wars figure absent so far that were included on the survey. Personally, I can't see those,coming in last. R2 also appears in the video in what appears to be more than a townsperson form. Boba Fett's helmet is also featured in one of the videos talking about Avalanche's work BTS. Coincidence?
So, I think the Force Awakens set will include Rey and Kylo, with Finn, Phasma and R2 as add-ons. I also think we will see Boba and Calrissian (he's shown in one of the sketches in the videos from BTS also).
On the Marvel front, I think we will see Scarlet Witch and Vision (since both appear in Ultron and Civil War), and possibly Winter Soldier or Strucker.
The next wave of Disney is likely to be a Muppets Playset, with Kermit, Miss Piggy, Fozzie, Animal and Gonzo. Plus Alice.
Lastly, it's interesting they have added a "nurture" farming element to the game this time around. Doing this opens up characters who are not traditionally combat oriented, like Aurora, Cinderella, and the other princesses.
So much speculation!
I simply cannot wait for this release. Counting the days...
