No a SW fanatic but isn't Disney era SW a case of the fans hating whatever new movie comes out because nostalgia and nothing else could measure up to the old stuff? I know in Dragon Ball fandom DBS is disliked because it's just more of a okay/meh product and not because it's new, newer Pokémon games get hate because of a genuine quality drop and a lack of proper effort by Game Freak in terms of design because they sell no matter what.
It's a bit more complex than that. Star Wars fans are a hard bunch to please as you can see with Ahmed Best (Jar Jar) wanting to kill himself over the role or Jake Lloyd being derided as the kid to ruined Vader. Even George noted in an interview with the NY Times, “Why would I make any more, when everybody yells at you all the time and says what a terrible person you are?" because he got a lot of backlash from the Prequel Trilogy.
The Sequel Trilogy was rocky to begin with since Disney did some unpopular choices such as render the Old Expanded Universe as Legends. If you are familiar with the Old Believers of the Russian Orthodox Church, that was the type of schism that happened with that decision. By the time Sequel Trilogy actually went into production, the studio had to play the balancing act since we have two generations of fans: those alive around the Original Trilogy, those who were introduced with the Prequel Trilogy, and of course new fans in general. It's a difficult but not impossible balancing act to play.
Of course, when it actually debuted, we got a bunch of reactionaries writing essays about how Star Wars is "too political" which anyone who has seen any of the Prequel era media will just say, "That's the point."
Okay, let me ask the questions about the as-of-Currently non-existent Pokémon Gen 9 Anime
1. How will Ash Go to the Gen 9 region even if we are still in Pokémon Journeys?
2. Considering Ash has a recent friend.... Goh, Will Ash get a new friend again considering he has now retired as a Pokemon trainer but he becomes a Pokémon Master off-screen?
3. Whenever Game Freak is doing with Gen 9, will there be a major Villainous Team exclusive to now-nonexistent Pokémon Gen 9 Anime?
4. What would Gen 9 Starters look like?
5. What would Pokémon Professor in Gen 9 look like?
1. If you keep the world tour, they'll just make it another stop on the touring aspect. Kanto still takes precedence if previous trends are still present.
2. What?
3. That depends on how it's played in the games.
4-5. That's a bit outside the scope of the information we have at the moment.
