Will Infinity War signal the beginning of the end.....

I think so. I love the MCU, but eventually it will have to reboot. Iron Man and Captain America are the main attractions and I can see both leaving after IW. If so, Spiderman would still ring in the crowds, but can Ant Man, Black Panther, etc. do the same? I am not really sure. I LOVE these movies and even I am getting fatigued.
