Well, this snuck up on me. Nintendo has just had a Direct stream for Japan only!
Announcing 'new' 3DS
variants (with NFC and second analogue 'C-Stick' like the GameCube nubbin - CALLED IT!), a new character for Smash Bros.
(which is a given at any Nintendo event nowadays), free add-on content for Hyrule Warriors on launch, themes for the 3DS home menu (sych as backgrounds, icons and sound effects!), a free soundtrack CD when you register both versions of Smash Bros. on Club Nintendo and probably other stuff that I can't be bothered to look up as I'm at work.
