Captain America & Tony Stark actually need to be in a solo movie together and its about time. In the comics these 2 dysfunctional relationship play a big role in not just the Avengers but the entire universe. Thor & Black Widow, Hawkeye etc …do not hold the same weight as these 2. I’m sorry to say it like that but they just don’t. Plus Iron Man & Captain America have the best solo films in the MCU. Another reason why Marvel/Disney/Sony are rumored to try & work out something for Spiderman because he to has a significant role in this story arc. As much as some people don’t like it, Tony Stark is a huge part of Marvel Comics & Films. Like Batman he also finances the Avengers. Captain America is the leader. It’s sort of like a Batman/Superman thing. These are the 2 most popular Marvel hero’s in this world(minus Spiderman). Its only right they appear in a solo film together. My thing is wait & see where this goes. They probably will most likely not adapt the same civil war story in the movie. Marvel(like they always do) are probably planting the seeds to this story for more buildup. There has been buildup to this story since the first Iron Man movie. I don’t think Marvels plan is to throw other actors aside but to tell a overall story arc.
