SourceToday, the South Korea GRB (Game Rating Board) apparently approved Crysis for the Xbox 360. Crysis has not been released on the Xbox 360. It's a Windows-only title.
According to the Korea GRB, the game will be published by EA Korea. The rating page, which also went live today, specifically states the game is Crysis. Crysis 2 was already released in South Korea earlier this year. Does this all mean the Xbox 360 is getting a Crysis port?
