A leaked logo revealed the existence of a third Mario & Sonic Olympics game last week, and now Sega has confirmed it in a press release (having also sent out an official, much cleaner-looking version of the logo).

Mario & Sonic at the London 2012 Olympic Games is skipping DS and going only to Wii and 3DS. New Olympic events for the Wii version include soccer and equestrian challenges, along with a new slate of less realistic "Dream Events." The 3DS version has "over 50" events, none of which were named.

In addition to those, the title is a marathon on its own.
