I think they are moving to a new Avengers lineup which would possibly include - Ant-Man, Wasp, Black Panther, Captain Marvel, Falcon, Winter Soldier, and Wanda with perhaps Spider-man and Dr. Strange as fill-ins. Clearly BP, Captain Marvel and Ant-man are going to be the biggest parts to this, what I don't know is how much Spider-man and Dr. Strange would be apart. Peter is still a teenager, so I think he would be an associate member, and Strange already has a full time job as sorcerer supreme so I don't see him being a full time member, but someone that would assist.
I also think Vision is going to come back. but that's another thread. I also hope they bring in Wonder Man
