"SEGA AGES aims to bring prominent titles from SEGA's legacy catalog to fans around the world", an official message from the company reads. The new Switch Sega Ages games will be the work of retro masters M2 (who also handled the original Sega Saturn releases).
The Pokemon Company has not officially announced anything that would be deemed concrete information for its upcoming PokemonNintendo Switch game. M2 was the studio behind a wide range of "3D Classics" releases on the Nintendo 3DS, so it definitely has a lot of experience working on Sega's classic games.
Sega Ages was a series of retro compilations released on the Sega Saturn back in mid-90s. "Translating the Pokemon featured text we get this in English: "After a lifetime associated with portable consoles, the canonical pokemon will take the leap to a table with its eighth generation. game freak and the pokemon company are rethinking the saga to surprise with new mechanics, either in 2018 or later". The Sega Mega Drive Mini is actually a mini version of the Genesis, which was sold as the Mega Drive outside the U.S. The SNES Classic console was such a hit this past holiday season that Sega probably envisions a similar fate for its nostalgic mini console. It didn't announce a price either. The console looks just like a mini Sega Genesis console, although it doesn't hold cartridges like the original model did.
