Jump Festa 2012 will have Square Enix, Nintendo, the Pokemon Company, Etc

Jump Festa will be happening on December 17 (which is the Playstation Vita launch date) in Japan. Though it is a manga and anime convention sponsored by Shueisha (the company behind Shonen Jump Magazine, and therefore, manga like Bleach, Naruto, and One Piece,)  it is also a gaming convention where Namco Bandai and Square Enix usually attend.

This year is no exception since the RPG giant will have their upcoming Kingdom Hearts 3D playable at the event. Nintendo will have their Mario Kart 7 in their booth. This year marks the first time the Pokemon Company attends the event solo.
