What's Nintendo working on? Even more Wii and 3DS games.

DS Harlequin is by Genius Sonority.

X-Scape = 3D Space Tank by Q-Games.

You can probably attribute Wii Vitality/Relax/whatever to EAD, even though we don't know which specific team yet.

Hoshi no Kirby Wii and Legend of Zelda were both also recently reconfirmed as happening.
