Quote: The FAQSkylanders Imaginators comes complete with a character creation system that allows you to combine appearances, powers, abilities, names, catchphrases, musical themes, and much more to create the wildest Skylanders imaginable. Many of these options will be available as soon as you fire up the game while others will unlock during the game's campaign. Once characters are created, players will be able to store their new creations inside an elementally aligned Creation Crystal that they can take with them to other systems.
Musical themes? Maybe that's something similar to villain themes?
Also, don't remember if it was confirmed yet or now, but on the FAQ, it mentions the consoles, and 3Ds and Wii aren't mentioned.
