Doesn't surprise me to be honest. I really hope they pull it off and release the game properly, not the pre-alpha that is available now, but I can't see it happening.
From my understanding they used completely the wrong game engine for a game of this scale. Cytek/Lumberyard is not really suited to that kind of game from what I can gather. Probably would have been faster if they developed a game engine from scratch that can tackle this kind of game instead of trying to retcon one that is not right for what they want to do.
Its funny, because if you go back some years, before things started to drag on and on, and before the court case, if you dared to suggest that they would have been better off developing a custom engine, the general response was that CryEngine is a great choice, that CryTek are a good company, and that developing their own custom engine would have taken years.
And here we are now, with CIG largely having to rewrite CryEngine anyway to support what they need to do and the game still taking years longer than initially envisaged to deliver.
