YipeeXD are you female? 

Also in regards to the duel wielding thing. Each of use will get the option to duel wield later on. My theory is that if a person that already has a keyblade picks up another and their heart is strong enough that the old keyblade, being a shell of its former self, will flair to life in a new form with new abilities that will match the heart and ideals of the person. So no one will be able to starting out but later Master Yen-Sid will have something for everyone.
