As much as I really don't want to say it, there is a high likelihood that Biden will become the next president, which will most likely mean that China will be more assertive in becoming the dominant economy, unless something big happens in the U.S. where change is done (highly unlikely that many people will try to do anything about it).
Assuming everything goes according to plan for the globalist elites, I predict that the American entertainment will primarily focus on China as the main demographic for their movies, games, etc even more so than currently, while the properties that are smaller in budget and/or not popular (and most likely would never be popular) in China will be made into entertainment that solely focus on minority (primarily black) characters. For all potentially profitable IPs, China will be the main setting and/or the main characters will be Chinese, and the glitz and glamour of the conventions like San Diego Comic Con will be removed from conventions in the states and focused in Chinese entertainment conventions exclusively. As we are already seeing, minority characters are taking on the mantle of classic comic book heroes. I foresee this continuing, with these entertainment companies fully willing to lose money on Western-focused mediums, seeing the losses as justified in exchange for good PR by the media and the growing minority community that likes terms like "Latinx" and other woke appeasements. Of course, all of big budget films and TV shows will be made with China as the sole market, so black characters will be minimized as much as possible. They will become fully confident they will make even more money with Chinese-focused mediums and thus offsetting potential losses. Overtime, the American market will stagnate thanks to wall street extracting America of its resources and thus corporations will make America a secondary market that would no longer be profitable, instead becoming a market purely for accruing brownie points and diverting attention away from unethical dealings in China while American politicians pretend that the United States is still the dominant force.
Most of these predictions are probably not really predictions as this is already happening now, but I only see it getting worse if American continues down the path it is going right now. Where do you all see the market focus going, assuming nothing changes?
Entertainment will be the least of our concerns starting next year.
There will be much bigger problems we face.
Hard times create strong men. Strong men create good times. Good times create weak men. Weak men create hard times.
Guess where we are in the cycle.
The CCP will centralize all non-woke entertainment under Tencent Pictures and tell everyone else to go full SJW.
I don't think it will be quite as drastic as you describe, but the big budget movies are going to become a lot more like the later Transformers movies and Pacific Rim 2. Even if they don't include a Chinese character or an excuse to have some scenes in China, there will still be something like Japan getting destroyed or using a map that gives them more territory/doesn't include any country they don't like.
