The Russos haven’t ruled out the possibility of Netflix super-types like Daredevil or Jessica Jones coming to the aid of Earth’s Mightiest Heroes. “We do consider everyone,” said Anthony Russo. “We don’t want to get too specific about what’s going to happen with these movies. We want these movies to be a surprise for audiences.”
I kinda expect The Defenders to cameo on the movies. Or at least, one of these "strangers" watching the destruction is Frank Castle or Foggy (if they don't want to show the main characters), they have literally NO excuse to ignore the Netflixverse.
So much news this weekend more so in relation to the Marvel series but Doctor Strange is coming in less than 4 weeks, Iron Fist in March and then GOTG in May
