Nintendo held its Fall Conference this week, and the company has revealed some interesting news about its upcoming games. Some of the biggest news of the conference is the announcement that Super Smash Bros. Brawl will include Sonic the Hedgehog as a playable character. While Sonic's been long-speculated as a character in SSBB, this is the first time his presence has been officially confirmed. Unfortunately, the game itself has been pushed back in Japan until January 2008, which could mean that an American release will also be pushed back until next year. In other news, the new Mario Kart Wii game will include motorcycles, a new Pokemon game will hit the Wii in the form of downloadable content, Wii Fit will retail for 8,800 yen in Japan when it ships December 1 in Japan (suggesting a U.S. price tag of about $80 and a ship date of Q1 2008), and Mario will be getting his own Wii baseball game in the form of Super Mario Stadium Baseball. It's an exciting week for Nintendo fans. Read more in Kotaku's Nintendo Fall Conference roundup.
