Square-Enix's official French store briefly listed Kingdom Hearts 3D: Dream, Drop, Distance for release on July 27 before the company pulled back the listing and replaced it with "Summer 2012". Either way, it's a more precise release window than what we'd heard before.
Square may be pulling back the Western release date just to give itself some wiggle room in case problems arise with shipping the game. Europe typically sees Friday releases, which July 27 is; that could mean Kingdom Hearts 3D hits North America on July 24.
The game arrives on March 29 in Japan.
