"I think DJ Hero is a really innovative product," he told Game Informer of the $100-plus peripheral-packing music game, which hit in October 2009 to critical praise but modest sales. "I can't wait for you to see next year's. We'll stick with it and get it right."
As the interview appears in the Game Informer issue that's just now hitting subscribers (meaning the interview was presumably done in 2009) and Kotick is big on annual iterations, it's likely he was referring to a 2010-due sequel as "next year's."
Kotick added that the company's new strategy is "going to be less games, better games," marking an abrupt shift from the previous more is better stance that is perhaps best evidenced by its former plan to triple Guitar Hero offerings between 2008 and 2010.
