During a call to investors today, Ubisoft CEO Yves Guillemot announced that a new Assassin's Creed title is coming next year, and after announcing its development, refused to say any more regarding it.
However, he did say that pre-orders for Assassin's Creed: Revelations were "significantly higher" than figures for Brotherhood, yet the firm is still expecting a "double digit decline" in sales for Revelations compared to the other title.
"We want to be careful and prudent, but we have high expectations for the product," Guillemot said, according to Gamasutra which was listening to the call.
Sales for Brotherhood were "in line" with Assassin's Creed II, which sold close to 9 million copies worldwide through March 2010. Brotherhood has sold 3.14 million copies in the US through the end of September.
The Assassin's Creed franchise as a whole has moved 31 million copies since November 2007, and the number will obviously grow once Revelations is released later this month.
