That's the only hope remaining. Masuda said that "their policy will change for the future games", adding that "they will pick and choose what pokemon make sense for the experience". S&S are doomed in that regard. They will not be changing anything about the games and a patch is not a possibility.
Let's just hope that they understand how bad this is (preferablly through bad sales, although highly unlikely) and rectify their mistake in the next games.
