The main highlight for this years Jump Festa was definitely the Square Enix booth, where a huge chunk of their upcoming lineup was on display, including Kingdom Hearts II: Final Mix as well as a trio of games never before shown in playable form -- Crisis Core: Final Fantasy VII for PSP, and Seiken Densetsu: Heroes of Mana and Final Fantasy Crystal Chronicles: Ring of Fates for Nintendo DS. Unfortunately Final Fantasy XII: Revenant Wings wasn't playable, nor was the recently announced update/port of Final Fantasy Tactics: The Lion War for PSP (though they did show a nice video).
SE also had a private movie theater showing footage from many of their 2007 games, including Final Fantasy Versus XIII for PS3 and Final Fantasy Agito XIII for cell phones. Interestingly enough, at the end of the reel they showed a very brief (like one second brief) clip of the face of an armored man grimacing at the camera on what looked like some sort of battlefield. It was followed by the text "And something new coming in 2007." What it was is anyone's guess; Time will tell.
They also showed a new trailer for Dragon Quest Swords: The Masked Queen and the Tower of Mirrors for Wii, which will be the first Dragon Quest game ever in Japan to feature voice acting (the US version of Dragon Quest VIII was fully voiced, but the Japanese one was text only).
