There's going to be a Lone Ranger level of Toy Box Takeover??? YES!!!
I think Syndrome is an interesting villain; he can't be serious and dangerous, yet he also whines and wipes his nose (I'm not kidding)! Chernabog would've been an interesting choice since I've heard him referred to as the most dangerous of all the Disney villains. If Maleficent wasn't in 2.0 as a "hero" she would've been a great pick for the wand-thief. Like in Fantasmic!, she could turn into a dragon at the end for the final battle. That would be so cool!
But I'm looking fora ward to TBTO all the same. I know it's going to be AWESOME!!
I'm sure the team is hard at work to make sure that if the game does get quadrupeds/water mechanics that it's done right and it's done awesome! I have faith in them.
