I think it won't to be the next Fortnite, and that won't be as 'revolutionary' as were Halo or Destiny because the MP shooter market grew a ton, there's a ton of great competition and Bungie is rejecting their PvE only fans for Marathon, which will prevent Marathon from breaking the Helldivers 2 launch record.
But I think will be very successful, specially in the long term as they keep tweaking, improving, fixing and expanding it over time.
I think it will be the game that opens the extraction shooter to the masses being the first that makes it successful outside the super hardcore niche, and the first makes the subgenre very popular in console.
I think once people plays it enough to understand it most of the people criticing it now will end loving it. I think will get huge in Twitch and that will get people mostly from Destiny 2 PvP, extraction shooters, Apex Legend, Fortnite and PUBG.
I also predict that several of the doomers that are calling it a Concord 2 or Skulls & Bones 2 will become a meme and people will laugh at them.
