Here's a list of movie releases in 2018
http://www.imdb.com/search/title?yea...ease_date,desc
So, let's narrow the list down a bit.
First let's remove anything not "global renown", i.e. anything new(ish). That leaves us with ...
Deadpool 2
X Men Supernova
Kung Fury II: The Movie
Iron Sky: The Coming Race
Death Race: Anarchy
Goosebumps 2
Jay And Silent Bob Reboot
Creed II
Power Rangers 2
Iron Sky: The Ark
Avengers: Infinity War
Black Panther
Fantastic Beasts and Where to Find Them 2
Tomb Raider
The Predator
Pacific Rim Uprising
Ocean's Eight
Ready Player One
Aquaman
M:I 6
Jurassic World Sequel
Incredibles 2
The list goes on, but those are the most notable. It is very probable I've missed off what film it is, but in that list, I think we can remove anything that will be developed by another games studio. Disney for example have their own games studio, so anything they own (and that is a lot of stuff) is probably not Frontier's 2018 release. That leaves us with ...
Kung Fury II: The Movie
Iron Sky: The Coming Race
Death Race: Anarchy
Goosebumps 2
Power Rangers 2
Iron Sky: The Ark
Fantastic Beasts and Where to Find Them 2
The Predator
Pacific Rim Uprising
Ready Player One
M:I 6
Jurassic World Sequel
I also removed anything I don't think will be made into a game.
My best guess is Frontier are going to do the game version of Ready Player One. It's a film of a popular book. It's not had a game made of it yet. And Frontier love their sci-fi.
