It actually makes sense, next gen consoles could run it comfortably.
------------------------------
As for a New Crysis game.... Crytek are very much alive and kicking, they just released Hunt Showdown to console, their engine is getting major quarterly updates, currently on 5.6, i use it, its a good engine....
Road Map It's getting Hardware Ray Tracing in 5.7.
I don't know what they are currently working on but something is in the works and there have been subtle hints of a Crysis revive, don't count it out....
