I admit to being a little underwhelmed by the announcement of Phase 4. Obviously, they want to broaden the universe to incorporate fresh story telling with new characters, but the announcement had kind of a "throw some stuff against the wall to see if it sticks" feeling to it that has me a little concerned.
They made a **** ton of money off what they've done so far, so they've obviously got some cushion to play with with respect to fans and profitability. But I'd have been more excited learning more about the next Spider-Man, Black Panther, or Guardians flicks given how interwoven they are to the world we've come to know.
