Donkey Kong Country Returns developer Retro Studios is making a game for Nintendo's next home console, according to an online report.
Sources within the US studio told The Paul Gale Network the unannounced game is "a project everyone wants us to do".
Gale speculates that the game could be a first-person shooter. Retro Studios has pedigree in this area – it created the superb Metroid Prime Trilogy for the GameCube and the Wii. Could a new Metroid game be in the works?
Nintendo's next home console, codenamed Project Café and due out next year, is said to have high definition visuals and graphical power on a similar level to the PlayStation 3 and Xbox 360.
Its controller is rumoured to feature a touch-screen that enables the streaming of games played on the console.
According to a report by French website 01.net (translated for Eurogamer by Eurogamer.fr), Nintendo is courting Grand Theft Auto maker Rockstar in the hope that it may make a game – possibly Grand Theft Auto V - for the system.
Nintendo is expected to announce its new console at this year's E3 game show in June.
