As many had been expecting, Square Enix announced a more specific release time frame for Kingdom Hearts 3D at today's Jump Festa event.
In its coverage of the event at Twitter, Square Enix fan site Final Fantasy Reunion reported that the game is now due for release in March 2012. Square Enix had previously announced a general Spring timeframe.
FF Reunion also reports that there are no plans at present for a hardware bundle. This presumably means that a bundle was not mentioned in the game's Jump Festa trailer.
