In its fiscal 2006 conference call this afternoon, Activision confirmed that it is under development with and will have at least one game ready in the first four months of Nintendo's next generation console, codenamed Revolution. The publisher's CEO and chairman, Robert Kotick, said that the game would arrive in Activision's fiscal 2007, which ranges from April 2006 to March 2007. This could very well mean that the game will be a Revolution launch title, although the executive would not elaborate on a hard release date for the still-unspecified project.
IGN Revolution is able to confirm that Activision readied a Revolution development team as far back as October of 2005, giving it ample time to work on the still-secret game.
The company has a host of big-name licenses to draw from, including inevitable sequels in the Spider-Man, Tony Hawk, and Call of Duty franchises. The Revolution game in question could fall under one of these brands. However, it might also be a completely new IP catered specifically for Nintendo's innovative controller and platform.
I personally hope that the game is Call of Duty, the franchise would seem brand new with the Revolution controller.
