Actually the game's delayed til November 20th. Another female suggestion would be.. THIS!
In all seriousness, many people (including myself) have been speculating that the 3rd female character will be Gravity Rush's Kat.
can you put the name down? sorry that I can't recognise just by image.
It's Bridget from Guilty Gear.
Another suggestion is Monica Raybrandt from Dark Cloud 2/Dark Chronicle.
