I'm going to have to say you're wrong there, Ruby. Another easter egg was also in that image, but I didn't mention it, if you view the coding of the picture, at the very top, it says:
"Thirty Years Later, only One Left"
If that statement is true, it could mean two things;
1. That would mean that Freddy might be the only animatronic in FNaF3, since it won't be "FNaF" without Freddy.
2. It would mean the game is based in 2017, since FNaF2 is based in 1987, but yet again, that would contradict The Game Theorist's timeline, meaning that FNaF2 would be the latest date, instead of the original FNaF.
