I'd say we need more then a a bit of girl power, we need a lot of girl power!
This was the first real link I got when I searched for
Disney Infinity The Little Mermaid:
http://smartwhenshouting.com/disney-infinity-no-girls-allowed/The initial release is just Violet, Mrs Incredible, Jessie and Holly.
Vanellope, Mirage and Edna Mode are scheduled for later.
I'm not really counting Edna though, since she doesn't have any real powers or fighting abilities.
Also, I'm a little puzzled by Nightmare Before Christmas.
Most sets will give you two characters, because Worlds are restricted to franchise characters.
With this one, you only get Jack.
The other main character from that franchise happens to be female, so where is Sally?
Hopefully they'll start work on some of the other more femalecentric characters once the game is established.
I really want Ariel, Mulan and Meridia.
Sally (Cars) and Sally (Nightmare before Christmas) would also be appreciated.
As for Calhoun, I'm not really interested in her, since she's a secondary plot character.
But I'm not opposed to the idea of her being included.
All the other female characters I want belong to TV shows (example, Kim Possible) and they've never really discussed if Disney TV shows will be included in Disney Infinity.
Wait, why does that poster say June 2013?
I have a release date of August 2013.
