Only those seven characters in Graces? I certainly hope that's not true. I mean, I'm obviously still hyped for the game regardless, but it seems a little lacking on the female side of the roster. It really needs a fourth female character to even things up, even if she's not the loli I'm still vainly hoping for.
Of course, what would be kind-of-awesome is if they act like that's the full roster, then pull a surprise character (or more!) on us when the game is actually released. It would make a change going into a Tales game without knowing the whole party in advance for once >_< That's probably an even vainer hope, though =p
