I don’t know about all that. It’s already been reported that Disney is going to make more money off Black Panther than Civil War and Age of Ultron.
It’s all about money at the end of the day and even though worldwide Black Panther will come in 3rd behind Avengers 1&2, studios make more money from the domestic box office and Black Panther will pass Avengers to be #1 superhero film of all time domestically next week.
I do agree the release date push was to give Infinity War another week to itself but Disney don’t give a damn where the money come from.
Black Panther will most likely beat Infinity War domestically anyway.
When I say they don’t want BP to make more than IW I mean from a business standpoint, not a racial one. It doesn’t look good if IW grosses less than BP. Just like if it grosses less than Ant Man or Dr Strange or Spider-Man
