I saw a couple of talking heads saying that the "win" for the Manhattan DA isn't quite what it's portrayed as - the gist was that POTUS does not have total immunity from state prosecutors, but there's a high bar and various legal arguments are still available to the DA's target (e.g., Trump or any other future POTUS) when it goes back to a lower court.
IANAL and I don't completely trust things I see on TV from either side, but I suspect this little bit of drama isn't over yet.
