Will Avatars box office dominance decrease as more of the movies are released

Avatar 2009 is the highest grossing movie of of all time(2.923 billion to be exact). Avatar: The Way of The Water was released in December 13 years after the first movie. In February ATWOW(2.310 billion) became the 3rd highest grossing movie of all time surpassing Titanic and Avengers Infinity War. Avatar 3 has already finished filming and is believed to release the week before christmas in 2024(the release week is predicted to be the same for the rest of the movies just 2 year apart, 2026 and 2028). While I do believe that the rest of the Avatar movies won't flop compared to the first 2, it might be slightly unrealistic for them to continue hitting 2 billion in the box office.

I am in no way saying that the rest of the movies won't gross in the billions because I believe they will just 2billion+ is what I'm questioning
