I think that Fortnite will be still on top because of things that owners of this game do for a community. I heard that they are promoting the game with for example streamers which they pay for playing it. They have a lot of audiences and encourage them to play together.
Also, the main thing you mentioned in the article - the mobile platform will be a good move. There is a big amount of people who want to play games on mobile devices.
Thanks a lot for this article and I'm waiting for full version on my iPhone 7 (hope it will be working on it).
