While I understand being disappointed, I really think it’s essential to clarify that, if the rumors are true, it’s possible that Universal never HAD FNaF.
I mentioned that Universal pitches a house to the IP holders, and that pitch will include elements of a treatment and concept art. The development of those things are, on rare occasions, how rumors start. But just because stuff was developed this early, that doesn’t mean that stuff was agreed upon or locked.
