Fixing the game is possible, but can we trust EA and current dice to make that happen when they're already talking about the next game not even a half year after 2042 dropped?
They'll probably do enough to keep a lawsuit from happening but nothing more than that.
I know it sounds bad they're discussing the next BF game, but realistically, that isn't coming for at least 2-4 years, because that's how long it takes to develop these BF games. And when it comes to these major franchises like BF, COD, Assassins Creed, etc, they always start planning the next game immediately after launch anyways, so this isn't anything new.
DICE said this last week that almost their entire studio is working on 2042 fixes and upcoming content. And last year they said they plan to support the game for "years" despite the negative feedback. So there's some good indication in all this.
I'm not saying DICE will save the game, they most likely won't since most of their old talent from BC2-BF4 glory days is gone, but if they do, there is a decent 8/10 game once everything's fixed and they add more guns and maps. Right now in its current state, the game is more like a 5/10 or 6/10 imo.
