I can understand though that Crytek is pissed, was talking with a buddy about that yesterday, apparently a good bunch of their best engine developers switched from Crytek to Cloud Imperium (mostly because Crytek simply couldn't pay them), and the "Star Engine" has received way more development than the current CryEngine (obviously). There's the chance that Crytek is afraid that they'll take their hard achieved knowlegde and make a new engine on their own, that's just guesswork though. It's surely going to be an interesting case.
