Namco is shelving the project before ever revealing it to the public.
Recent online reports have indicated that Namco is in development with a new Pac-Man themed pinball game for the Nintendo DS. Today, a Namco rep confirmed to PGC that the game was in development, but that is no longer the case. The title has been canceled, apparently early in its development cycle, since no screenshots have yet been shown to the public.
Pac-Man Pinball DS was to be the sequel to Namco's recently released Pac-Man Pinball Advance for GBA. The formal title of the DS game, according to IGN DS DS, was Super Pac-Man Pinball.
Namco still has at least two more Pac-Man games in the works. Pac'N Roll is due out this summer for the Nintendo DS, and Pac-Man World 3 launches this fall on GameCube and other consoles.
