A post by Scott Cawthon on Steam discusses the future plans of the Five Nights at Freddy's series creator, while also revealing that the heart of the story from Five Nights at Freddy's 4 has not yet been uncovered by the community (thanks Kotaku via nin). He describes a patch to come to Five Nights at Freddy's 4 on Halloween with new content and refinements, and also teases something different that will come at that time. Word is: "I'm hoping to have something else in addition to it, but it may not be ready. I have something fun in mind, a new game (not FNaF5), but it will be a real challenge to have even a small playable portion by Oct 31st. If a playable demo isn't ready by then, then at the very least there will be some sneak-peak content." He also notes that while the stories from the first three FNAF games were quickly sniffed out, the latest game has proven more difficult to crack:

You know, when I released the first game over a year ago, I was amazed at how quickly everyone found every bit of lore and story. Then the same happened with part 2, fans and youtubers dug in and found everything. Game Theory did an incredible video on part 2; getting almost everything right. Then part 3 came out, and once again the story was uncovered by the community. It seemed that there was nothing I could hide!

But then I released part 4, and somehow.... no one, not a single person, found the pieces. The story remains completely hidden. I guess most people assumed that I filled the game with     random easter eggs this time. I didn't. What's in the box? It's the pieces put together. But the bigger question is- would the community accept it that way? The fact that the pieces have remained elusive this time strikes me as incredible, and special, a fitting conclusion in some ways, and because of that, I've decided that maybe some things are best left forgotten, forever.
