SEGA has told Videogamer.com that they once considered launching a peripheral together with Mario & Sonic at the London 2012 Olympic Games in the early days of development.

“In the very early stage of this project, we even considered creating a new peripheral that works – that matches best for this game. We always try to look for new alternatives or possibilities.”

No information was given as to what the peripheral may have looked like, what its function was or which platform it was for, but with Mario & Sonic’s brand power and SEGA’s success with past entries in the series, their new game doesn’t really need peripherals to sell it anyway.
