Crytek and EA are apparently working on something together. According to a job listing posted on EA's career site, the publisher is looking for a video editor to "embed with partner studio (Crytek) [sic]."
The job posting requires applicants to have "significant experience as a Cinematics Director" and "challenge the paradigm of video game trailer creative." Now presumably, and I could potentially be wrong about this, we can expect some sort of trailer if Crytek and EA are indeed working on something new.
It'll likely look like a beast on PC as well.
The Crysis developer revealed to CVG a while back that the studio do fully intend to make a third game in the jaw-dropping sci-fi first person shooter franchise. Crysis 2 released earlier last year on PC, as well as PS3 and Xbox 360.
