The Spanish publication Nintendo Accion recently teased that SEGA may be prepping a new Mario & Sonic at the Olympics sequel set to revolve around the winter games. It is apparently going to reveal much more about the project in next month's issue. Naturally, scans of the magazine set off a flurry of speculation about whether or not the rumor is true as soon as they hit the Web, and SEGA's official statement is only that it does not comment on rumors.
IGN's done a little digging, though, and has independently confirmed that the game is in development and set to be announced in the next month -- which, by the way, really isn't hard to believe given the astronomical sales figures for the first title in the franchise.
Look out for more coverage on the sequel when it's officially unveiled. Until, let the speculation wars rage on about which winter games will and won't make the cut, and just as importantly, whether the title will support Wii MotionPlus, as we all hope it will.
