Unfortunately, there doesn't seem to be any new info aside from AC and TP coming back to the battle system and Lulu pretty much being confirmed non-playable by being categorized as a Key Character together with Elle. And, to those who missed them from our previous post, Ludger and Elle's official names are Ludger Will Kresnik and Elle Mel Mata. Also, Lulu.
Fun fact: Lulu is a male cat.
Also, unlike the previous sites for Tales games, Xillia 2's site is more HTML-based, and not Flash.
