Okay. I was look at the character list for 1.0, 2.0 & 3.0 so far after the Twitch livestream today (There will be over 100 characters after the release of 3.0) and currently; we're at 90 characters (with the Crystal variants). Considering that, here's what I consider to be the possible list of final characters for 3.0.
EDIT (11/5/15) - I've added more characters after reading some of the comments plus some I've thought about recently. :3

Kylo Ren
Captain Phasma

Zeb
The Inquisitor

Scarlet Witch

Ant-Man (Film out in July)
Daredevil (Netflix show)

That would bring the character count to 110 characters to date and would make this version of Disney Infinity the biggest to date. What do you guys think?
