Steam's autumn and winter sales reportedly dated

Steam's annual sales for the autumn season will run from Nov. 21 through Nov. 27, with the holiday sale going from Dec. 20 through Jan. 4, according to Artery Studios CEO Tamás Bakó, reports Joystiq.

Bakó said Valve contacted him about featuring his company's 2010 horse breeding game, Secret of the Magic Crystals, in this year's seasonal promotions. A different indie developer gave Joystiq the same dates listed above out of an email the developer received from Valve.

We've reached out to Valve ourselves to confirm the dates, and will update this post with any information we receive.
