They already did with FFX-2. All 3 of the main playables were female - and it was an excellent game

Yup, same goes for me and my peers who have picked the game up.

Spring 2015 is just as crowded now:
Arkham Knight, Battlefield, Witcher 3, Mortal KombatX off the top of my head.

5th Character - Handsome Jack Body Double

What's using the other 49.95 Gigs of the blu-ray?

I got this game dirt cheap for $10. Totally worth $10. Not one bit disappointed that I got my value from the game.
