This is kind of what I think. I feel like OW2 as it stands is just going to be a FotM game that loses a lot of Overwatch players and doesn’t retain many new players.
The PvE might bring some new life into it (since it’s supposed to only have a few months to go?) but I feel like it’s going to be very… episodically released and priced. Why would Activision-Blizzard sell an actual game if they can sell an entire game’s worth of missions to you one mission at a time? If the PvE is as hurriedly put together as the PvP was, I feel like it’ll have the same issue with player retention.
The game will always probably be profitable, but Activision-Blizzard now has a track record of just shutting down a profitable game they run, so if it isn’t making enough profit I could also easily see them discontinuing support or outright turning the servers off.
