Avengers 4 rumoured to take place 5 years after.

It's not the first time I read about this. An article I read some ways back described how the Avengers are now broken, each doing their own thing. Cap has built the Secret Avengers, working underground to fight off threats without the backing of the government. Thor is with his people, trying to start their life anew while fighting off discrimination from people of Earth. Tony is obsessed with finding a way to bring back the people that Thanos killed off. Can't remember what the rest were supposedly doing. Not sure how true it is though.
