As long as the Marvel machine makes money, they will continue to look for areas to make movies. And if people are interested in that 5 year period, they will as sure as shootin make tv shows and movies covering that area.I'm not sure they're going to spend that much more time rehashing the Blip.
I am personally really hoping for a solid movie within that time period, because honestly it must have been horrific. This is civilization ending levels of devastation, entire infrastructures would have been lost. Mass depression and suicide, revivals of religious cults, talks of the rapture. the geopolitical landscape would change overnight, and concerns about nuclear strikes and "which country is responsible for this". The remaining avengers must have been insanely busy keeping various threats from exploding.
Quite frankly, the fact that things are decently back on track ONLY five years later is pretty crazy.
There are a million stories you could tell in such a time period.
