Crytek have nothing to do with this game though do they? Im guessing money has changed hands regarding licencing and whoever takes over Cryteks assets will just get what ever cut had been arranged.
CIG have customised the source code for the Cry engine that they used, although I can see it hitting future development. Crytek aren't closing down from what I gather and TBH are probably looking at ditching their games section and focusing on the technology arm. They have 400+ employees, so it can't be cheap to run.
