I expect Fortnight to be the dominant player for a while. Its (1) accessible art-style and gameplay (2) mobile cross-platform play enabled it to topple PUBG from its throne within a short period of time.
EDIT: Combined two posts.
If there is any new entry to the market that will take over Fortnight, I expect it to make major improvement in the area of inventory management - in essence, not requiring the player to open a separate interface to manager their inventory. This will move the ease-of-playness of battle royale games much closer to where mainline fps games are now, and potentially open up its player base to a much larger audience.
have play pubg and fortnite more these days. i think i will enjoy when mode comes from skill fps or tps developer. the mode is good, exciting but the control and feel of the game is not so good when playing.
i want maybe re mercenaries or halo or gears or destiny or chivalry
I tried playing almost every popular BR, but everyone of them burned me out. I would usually end up walking/running 95% of the game and about 5% in actual combat. Fortnite is a little better in this aspect, but not much. and the combat can be a bit... clunky... compared to other games. Honestly, if Halo does have BR, I'm actually excited to see what they'll do. Their mechanics are more refined than Fortnite and definitely PUBG.
For now, it's just not my cup of tea. I mind as well get fucked in the ass rather than play Fortnite or PUBG (not that I would mind a nice gentle romp).
