I suspect it will also end up being very good (especially since EA/DICE are getting absolutely battered so they "need" to give this game all the time, effort and money they can if they want to redeem themselves and save the BF franchise) however, one problem, BF 4 despite its issues was a lot of fun and nowhere near as bad as BF 2042 launch/current state so the question is, will people care about BF 2042 by the time that happens? Especially since BF 4 was one of a kind/had less competition back then, these days, you've got a lot in the MP FPS arena.
So far, the only saving grace for this game is and will be the portal imo and I won't be surprised if dice/ea will bring more maps/content for them than the main game itself. The main game maps are pretty damn awful.
