Nintendo have apparently secured the licensing rights from Konami to develop a new game the Momotaro Dentetsu series to be released next year, although no platform specified: 3DS is likely. Originally on Famicom, the game saw sequels on PC Engine, Game Boy and Super Famicom and more recently appeared on DS and Wii. Hopefully I’ll have confirmafion soon. Thanks to Hero of Legend.

Edit: edited post as it’s Momotaro Dentetsu and not Momotaro Densetsu. Sorry!
