Cryengine is not very good so we'll see. Also it seems that they don't have the backing from any major studio.
It was also very slow at doing so, although, without technical knowledge, it's hard to know whether this was actually inefficiency.
I find it very ironic that Crytek's evil geniuses very successfully managed to market low framerates as a feature. /shrug
