Same here. The Avengers is their event movie series where the who's who of the MCU show up for that big crossover. Also, the Avengers have a long history of rotating team members/rosters in the comics. I don't know why they would not want to do that in the mcu. They aren't getting rid of it. A4 earned 2.6b and they aren't gonna put it in the backburner and have The Ultimates replace it.
