They need a Cyberpunk 2077/ No man's sky level overhaul and that simply won't happen.
In Cyberpunk's case, CDPR within months of the terrible launch, had a clear vision of what they want to fix and how they want their game to feel in 2.0. They gave us a roadmap and plenty of updates and they delivered on what they promised with an incredible 2.0 release and DLC, that honestly propelled the game into my top 10 of all time.
No man's sky basically released a new game in the decrepit shell of their initial release. Multiple decent DLC's later and it's one of the best success stories in gaming history.
With their Elden Ring title on the horizon, there's no way Bethesda is going to devote so many resources to fix a broken game. They also promised that Starfield will run in a new engine following backlash when they said it'll run on the same one. There's very little confidence now in Bethesda that their next game won't be a buggy mess. Fallout 4 sucked until mods fixed the game. Starfield sucks to this day and their next title probably already has significant development done to it that they likely can't scrap lol.
If they honestly thought this patch would bring people back, then they're as deluded as the diablo 4 devs are
