Grargar: While it was most likely EA's call to release them here (they are the publishers, after all), Crytek still retains ownership of the series.
From Crysis' EULA:
CRYSIS and all copyrights, trademarks, and all other intellectual property rights related thereto are
owned by CRYTEK and are protected by German and international copyright law and other applicable
law. Licensee shall have no ownership or intellectual property rights in or to CRYSIS, including,
without limitation, all copyrights related thereto.
JK41R4: Um, releasing it here was most likely EA's call, they're the ones who own the rights to the franchise. Crytek were just the Devs.
F4LL0UT: That's not completely correct in this particular case, as far as I know. I was once told that Crytek's deal with EA allowed them to keep more rights to their stuff than is actually common. Don't know if anything about that has changed over the years but I guess there's a chance that EA could not just release Crytek games whenever and wherever they want without Crytek's agreement.
Ah, I see, thanks for correcting me, then.
