Here's the thing about Gen 8, specifically SwSh:
The tipping point was the removal of Pokemon. That's what really got everyone in a frenzy. So much so that they put majority of them back not even a year later, despite there being no plans to do so.
Whatever's next should not have that issue because they definitely had far more than enough time to finish the rest.
Now, on a graphical level, it could look a bit better, since they can reuse the assets from SwSh, and then polish it up knstead of creatong from scratch. The SwSh DLC looks miles better than the base game.
