Marvel has been really tight lipped about any plans and probably will be until after Spider-man : Far From Home that comes out in July
so we're still a few months away from getting any official news
but what we do know so far
the next two movies are already in development and will start filming soon , both for 2020 release dates
those are Black Widow solo movie and The Eternals
so plan on those two movies next year , and the three that will follow.....................probably
and these next three movies we know are all well underway in their development as well , with writers and directors already attached
Dr Strange 2 , Black Panther 2 and Shang-chi
we also know James Gunn will be back with Guardians of the Galaxy , but that one will be a few years off yet as James Gun will be directing DC's Suicide Squad first
and it will probably be a few years before we see The X-Men and Fantastic Four
the next two
the next three , in no particular order
P.S.
if you don't know anything about The Eternals , don't worry , nobody does...................LOL
