Like or loathe the sporting combination of plumber and hedgehog, SEGA's preparing to unleash another round of Mario and Sonic at the London 2012 Olympic Games to coincide with next year's English medal-a-thon.

The Wii version hits North America on 15th November and Europe on 18th November, with the 3DS version a little behind in February. For some reason the Wii version will come in a yellow box — not gold, not red or blue, but yellow. Should certainly stand out from the crowd anyway.

SEGA also sent over some new screenshots showing the heroes showing their appreciation for the 20 million or so sales the series has accrued so far. No wonder they're happy.
