Where did you find this information? I like the name Dia, and the whole day/night thing with XIII and vXIII, but I'm not too keen on the surname "Walruva." Maybe they'll fix the name in our version so it looks less like a fancy name for a Walrus vulva (I agree with you, The Turk!)

Also, are we sure Dia's her name? Because why is Dia also Oerba's middle name?

And I've been looking closely at the stills lately, and Lightning seriously looks way too much like Cloud. It's kinda freaking me out, not gonna lie.
