Here are my predictions about what you might see in the movie:

The Withered are not the same as in FNaF 1 movie.

There was always a debate about whether the Withered were the same as in FNaF 1. I always thought they were different characters because of their appearance, and it wasn't until SOTM that it was finally confirmed that they are different characters.

And in the FNaF movie universe, it seems that this will also be the case.

In the final trailer, a Freddy's papers from the first movie were shown, but the interesting thing is that he was called “Freddy Fazbear Version 3.0.”

This could indicate that the animatronics from the first movie are version 3.0, so the Toys would be version 2.0 and the Withereds would be version 1.0, which would be the originals.

And this may show that, as William said in the first movie, he created the animatronics.

It will show Charlotte Emily's death in a flashback, and there may be a possibility that it will show the deaths of the five children, the MCI.

The deaths will surely not be very explicit, but there may be more blood this time.

so there may be more shocking deaths this time.

And since the Toys and Withered are different characters, they are surely not possessed and would be killing machines, especially the Toys, who may have been created or manipulated by that character played by Freddy Carter (whose name, according to the cast, is Michael... I won't jump to conclusions about this), but that character looks mysterious and little has been revealed about him, besides the fact that he will be important in the movie.

It's still unknown why the Withered would kill people. I think that Puppet may be manipulating the Withered or even the Toys.

I'm sure there will be a maximum of 8 or 10 deaths in the movie. I don't think there will be that many, but at least this time the animatronics will feel like a real threat.

Vannesa is traumatized by the horrible things her father did, and throughout the film, she faces those nightmares and her fear of her father while also having to deal with the animatronics and perhaps protect Mike and Abby.

Perhaps here we will delve deeper into the father-daughter relationship and explore her past further.

The first movie didn't reference the gameplay of FNAF 1.

Well, it looks like there will be references to gameplay here, and Mike will surely face the animatronics in the same way that we face them in the game.

He will probably only face the Withered.

There's talk of a cameo by a special animatronic, and many say it's Candy. I don't know about you, but I don't think it's Candy, although it's not that far-fetched. I mean, FNaCandy's is part of the Fazbear Fanverse, which is part of the real FNAF universe, so it could happen.

If it happens, it would be one of the best cameos this franchise could give, along with Sparky's cameo.

but one cameo I really hope to see is JJ (Balloon Girl).

I don't know if it will happen, but it would be great if there was a post-credits scene showing The Yellow Rabbit as springtrap

Well, this is actually more than confirmed: Balloon Boy is going to die, and all the fans are going to celebrate!

To finish, this is about how the movie could end up being

The movie will probably be just as mediocre as the first one, but it won't be that bad, and it will still be better than the first one and much more entertaining.

If the script really turns out to be much better. It's a bit ironic that the first film, which took eight years to make and was written by three screenwriters, ended up being bad, but the second, which was made in two years and written by a single person, is better.

This may be cause for concern to some extent, and although Scott has written bad stories, in SOTM he has shown that, when he wants to, he is capable of writing a good story

Those would be my predictions. I haven't talked much about the plot, but this time there's not much to go on, and I don't know what the main story will be like. I prefer it that way and not think too much about it because it will be a complete surprise in the movie.

Well, we'll see which things I said will end up happening and which things won't happen and will age badly. Time will tell
