other than whatever rumoured divisions and in-fighting b/w the tv and film heads, there is absolutely no reason why all these properties shouldn't be epically overlapping into one anothers worlds.
like i wanna see Defenders popping up in an MCU movie.
or Vision guesting on an episode of AoS.
or Coulson finally appearing on the big-screen again.
can u imagine a May & Black Widow confrontation? (u know that's how most writers would play that in terms of first-meetings-that-end-up-in-fisticuffs-only-to-develop-into-strong-bonds type shit).
or Jessica Jones trading quips with Tony Stark?
or the potential chemistry b/w Quake & Star Lord?

the potential for universe-building here is nearly limitless. what's the official word on why this hasn't happened yet? (he says before going to google it).
