I don't think FNAF is likely to be featured this year. That being said, if it does hypothetically ever show up at the event, it's a near certainty that it will be a stand-alone house. In recent years, it's been one of the most highly request IPs for the event, and it certainly matches the popularity of other video game franchises like Fallout and The Last of Us, if not exceeding them. Not giving it a full house would be a major marketing blunder, especially since it is allegedly difficult to negotiate for.
