So I found out through some console menu on google that contains the link to the five nights vid and through YT, It takes you to the first FNAF trailer. This could mean FiveNights was originally the old name or a placeholder after the main 3 was finished. Yes viewer, It's just like the stingray, It's discovered to be real at one time but is actually fake. However the Hall 9001 eyes featured in the trailer were to confirm that the animatronics eyes are actually lightbulbs. Thanks to information originally scott designed the animatronics with the hall 9000 eyes, The only animatronic that featured the 9001 model was freddy in the early steam page / part of the kickstarter. So yes, The original trailer for fnaf 1 was just the same as before but could be missing visual effects.
