If we are to believe a report on the Spanish game site HardGamer2.com, EA will be bringing Crysis to the Xbox 360.
Here is a Google translation of the article on HardGamer2:
"Finally Electronic Arts and Crytek have confirmed that Crysis will arrive at Xbox 360. The articles are many that we have read on the difficulties to program CryEngine 2, and that this are compatible as well in consoles, but EA has announced that will put the infrastructure necessary to make profitable the costs of development of this version. They have not specified a date of launching, but the producer does not want that it goes away beyond the first quarter of 2008, because it would not have sense to send it so behind schedule with respect to the market of the PC and would harm the global sales. Of the arrival to PlayStation 3 they have not meant nothing, adding that, they continue studying the different possibilities that the console of Sony offers."
Update 1: 28 December = 1 April in Spain , so the story has now been confirmed as a spanish prank.
