Sega has revealed that they are working on a third Mario and Sonic game, this time at the London 2012 Olympic Games.
The third game in the series will once again be a mini-game collection based off of many Olympic sports. The new mini-games announced include both soccer and equestrian, while athletic events and table tennis make a return. As with previous titles, Dream Events, an arcade-like mode where the events are turned into Mario and Sonic themed mini-games, will make a return.
The Mario and Sonic series will return to the Wii, and make its debut on the 3DS. The title will be developed by Sega of Japan. Previous games in the series have been successful, selling over 19 million copies worldwide.
Both the Wii and 3DS version will be released later in the year.
