Following the leaked temporary box art (shown above) for Mario & Sonic at the London 2012 Olympic Games on Nintendo Wii that hit the net last week, more evidence of the game’s existence has appeared in two reports. The first one from French website SEGA-Mag.com on April 14th claims that Spanish voice actor Fabio Tassone who worked on Mario & Sonic at the Olympic Winter Games has the new game listed on his online resume, but the only problem is that it’s not there, so if the report is true, then Tassone has since removed it.

The second report is from the print edition of UK trade magazine MCV, which Sonic Wrecks founder ArchangelUK says contains an article about Mario & Sonic at the London 2012 Olympic Games entitled “Will this be the biggest video game of 2012?”. In AAUK’s news story at Sonic Wrecks he reports that MCV’s article features an higher quality version of the logo than the one seen in the temporary box art, which could mean that assets for the game have already been given to some press out there.

MCV also claims to know this new Mario & Sonic game’s current release schedule:

“MCV understands the game could arrive as early as this Christmas.”

The last two games in the series have both released in the holiday season (apart from the DS version of the first game), so it’s kind of expected that this new game would follow suit, but it’s very odd for a major trade magazine like MCV to be speaking about an unannounced game so openly like this. It’s also worth noting that this article is currently nowhere to be seen on MCV’s website. Could SEGA be planning to reveal Mario & Sonic at the London 2012 Olympic Games soon?
