That site has been out for quite a while, but the info was released today like I mentioned a few posts above. And yes, it does take place in Ivalice! That's right, the Final Fantasy Tactics Advance (not PS1 version, only GBA version) world is the same world that hosts FFXII.
The main hero is Vaan and the lead female is Ashe. The combat system will have judges in it just like Final Fantasy Tactics Advance. Looks like I need to get into high gear with FFTA!
They may look like Tidus and Yuna, but they are still great character designs!
