Just a couple of days ago I told you about a very solid rumor regarding the development of a new Mario & Sonic at the Olympic Games, and today we have official confirmation of it, plus some extra details from Sega and Nintendo, if anybody was wondering. And just to make things clear from the beginning: no, there are no unexpected features announced for the upcoming Wii and DS title.

Developed by Sega of Japan, together with Shigeru Miyamoto, Mario & Sonic at the Olympic Winter Games will take players to lifelike Olympic venues where they can choose from the classic cast of playable characters, including new faces to the series to be revealed later this year. Among the included sports, we’ll have Alpine Skiing and Speed Skating – we’ll have to wait a bit to find out about the other sports.

The Nintendo Wii version of Mario & Sonic at the Olympic Winter Games will offer both co-op and competitive multiplayer play, while the DS version will use the wireless abilities of the handheld to turn the game into an even more exciting one. Also, Wii owners will be able to use the balance board for some of the events in the game.

“We are extremely happy to again team up with Nintendo and ISM on what promises to be another global success.” says Naoya Tsurumi, CEO, SEGA of America and SEGA Europe. “Sonic will partner with Mario once more beneath the spotlight of the legendary Olympic Games. Together they will face new athletic challenges that will provide gamers with more of the exciting experiences unique to this series.”
