The latest issue of Famitsu has a page-sized teaser for what appears to be a new Tingle game for the DS. Logic assumes that this will be a sequel to his 2007 RPG, Freshly-Picked Tingle's Rosy Rupeeland, which was only released in Japan and Europe.
As it's just a teaser advertisement that's really all there is to say about it - There's no information or screenshots at all, sorry! We expect Nintendo will formally announce the game soon enough, however.
In the meantime you'll just have to stare at the Famitsu ad until some info surfaces (Note: The text simply says Fairy?):
