It has always been hinted that Crysis is the first in a three part story, and after finsihing it I can say this seems very likely. Plus, Cevat Yerli hinted at this a few days ago in an IRC chat with the Incrysis community (the full chat can be seen here). Now it seems there is another hint of a little bit of news on the whole thing. Steven Bender who is head of the Animation team at Crytek, said at a recent event in Berlin that the second part will not only continue the story of the aliens and Koreans, but also improve on the graphics (somehow…). He specifically mentioned improvements to animations and facial textures. Their goal is to get the game feeling so realistic it’s like you are in a film. He also hinted that Crytek were working on another project, a rumour also fueled when they opened up another Studio a few months ago (source: google it you lazy people).
Well, You can’t fault them, it’s not two weeks out the door and they are already seeing ways to improve the graphics. Here’s hoping we get some more information soon and that we don’t have to wait 3 years for this second part to be released!
