Depends on how good it goes.
But maybe they'll just make it a Two-Part Trilogy and the first movie can stand on its own.
Maybe.
You gotta believe me when I scare you away, all that I wish for is that you would stayPersonally, I'm hoping all three movies will just tell self-contained stories, without much of a grand arc. Try to keep things relatively simple. Movie franchises today are way spoiled for serialisation, and the fact that we can even talk about having one movie to introduce the characters and the second to get to the really exciting stuff, rather than expecting the first movie to be able to do both in one go, is a testement to that.
@Another: Well, you've just gone and named the porn parody of this movie.
Visit my Tumblr! I may say things. The Bureau ProjectBehind the Scenes featurette:
Some interesting information in there. Among other things, it clarifies who the central characters are going to be.
Apparently one of them is just some random muggle (well "no-mag" as is apparently the 1920's American term) who manages to get himself swept up in the events of the movie. This is either an amazing idea or a terrible idea, and I have no idea which.
Also apparently the name of the American Wizard school is "Ilvermorny".

Also while I'm not sure how much relevance this will have the the Fantastic Beasts movies, JOI Rowling has been writing about the international Wizarding schools online so we now know that there are 11 major Wizarding schools throughout the world (though smaller ones do exist), and of these 7 have been revealed.
I suppose it's possible that each movie in the Fantastic Beasts trilogy will take place in a radically different location, and the locations of these schools could give us an indication as to where it could be.
Schools introduced in the series: Hogwarts - Great Britain Beaxubatons - France Drumstrang - Eastern Europe
Schools revealed by JK Rowling online
Ilvermony - United States (East Coast)
Castelobruxo - Brazil
Uagadou - Central Africa
Mahoutokoro - Japan
The last 4 are still unaccounted for.
So do you think this movie will only be canon to the other movies, or is it canon to the books too since J. K. Rowling was involved in making it?
Or maybe Rowling will just write a novelization so that that's canon to the books?
I've got fanfics for Frozen, Spectacular Spider-Man, Crash Bandicoot, and Spyro the Dragon.
I don't think it's been clarified, but for now I'm going to assume Broad Strokes canon to the books and absolute canon to the movies.
I actually think that's a good thing. JKR's a fantastic wordbuilder, but the world as presented in the books has long felt kind of small to me. Like, Voldemort's said to have been one of the worst Dark Wizards in history, yet as far as we can tell he didn't seem to have ambitions beyond Britain.
Not that Britain being conquered by the Magic KKK isn't a Very Bad Thing, of course.

My headcanon is that Voldemort did have long term ambitions of global domination, but not until after he had taken care of all the loose ends in England, the most important of which was killing Harry Potter.
Though I think it's more the depths Voldemort went in his mastery of dark magic that gave him his reputation rather then the raw amount of territory he ever meaningfully controlled.

Mothman is closer to the Northeast than Northwest (being from West Virigina). You've also got the Jersey Devil, I'm pretty sure people have claimed to have seen werewolves, and honestly Bigfoot or variants are claimed all over the place. Lake Champlain in Vermont has it's own version of Nessie, Champ. I'm not sure about anything that would apply to New York City, though.
