Online Japanese retailer Gamestar has let slip some more details about Dissidia 012: Final Fantasy, and among the features listed is a voyeuristic/watching mode.
Basically, what the mode does, is allow those who are not participating in some of the game's tournament-style features - basically those who are not fighting - to still watch as other battle it out.
Other features mentioned in the listing are improved wireless support; exchanging friend cards; create and exchange original quests.
Also, importing your data from the original Dissidia will allow you to carry your character level over and give you a nifty accessory for the trouble.
Square Enix is having an event on January 18, so hopefully more features will be revealed.
Yuna was also recently confirmed for the title.
