Ubisoft is expecting Assassin's Creed to hit five million unit sales in its fiscal 2007 to 2008 year, which ends March 31, 2008.

Describing current sales of the roof-top hopping back-stab-'em-up as a "record performance", the publisher's said that the game topped two and a half million sales worldwide in its first four weeks on shop shelves.

Apparently it's "the fastest-selling new video game intellectual property in the US ever".

Already released on Xbox 360 and PS3 (review), a PC version of Assassin's Creed is due to release next year. Hopefully in a more finished state than the console versions.
