If I thought for a second that the current images weren't place holders, I'd say bottom left is a chick.
Assuming we haven't seen all the new characters yet, I'd say it's a safe bet that at least 15 characters from MK9 are out. There is no way in hell you can do that without removing classic characters and pissing people off. Ballsy move by NRS... My list of characters I'd be ok with not having is now three. Freddy, Stryker, Kratos... If there really is that big of a gap in the cast though, yeah... might as well not even call it MK.
There is going to be a sXXt load of "You kept in X but not Y??!??!"
