A job listing for a senior animator on Infinity Ward's own website is calling for applicants with an interest in "next-generation technologies."
The mere mention of Infinity Ward tells us that the technology must be for a new Call of Duty title, though there is no confirmation of such a thing. A general message found elsewhere on the website clearly states that they are specifically looking for talent to work on "the world's biggest shooter franchise," with no mention of any other project.
The next title from Infinity Ward may also be an early indication that we can expect next-generation consoles in the next 2 years. Assuming of course that Infinity Ward and Treyarch are still taking turns in the development cycle of each new Call of Duty title.
