I didn't see this anywhere else (which means it IS somewhere else :-) ), but GameSpot has posted the following release date info:
JohanX
- Super Mario 3D Land - November 13
- Mario Kart 7 - December 4
- The Legend of Zelda: Four Swords will be available in the eShop from September 28, 2011 through February 20, 2012
- Mario & Sonic at the London 2012 Olympic Games - November 15
QUOTE said:Beyond game release dates, Nintendo announced that a 3DS firmware update later this year will give the system the ability to capture 3D video. The same update will provide new content for the system's Street Pass Mii Plaza mode.
