The New Super Mario Bros. 2 announcement was actually the last bit of news from the Nintendo Direct stream, so excuse me while I travel back in time.
On April 25, the 3DS will receive a new firmware update. The biggest significant feature of the update is a new file management system that allows you to move software on your Home menu into individual folders. This has long been a request for Wii owners, but sadly, it never came to pass.
At least now we can file all our Virtual Console games into neat, organized sections on our 3DS.
