Uncharted was already put on hold (not around) for 4 years, but it was in several conversations since Uncharted 4's reveal in 2013. 5-8 years of no Uncharted, along with Naughty Dog moving on with The Last of Us 2, Savage Starlight, or whatever they are working on and people will easily embrace a new Uncharted within the next decade.
I wish Sony took that same path with God of War or Ratchet & Clank instead of milking them to death. However with the recent revival of Ratchet & Clank and possibly God of War, Uncharted's return in a successful way in the foreseeable future might not be impossible.
For now, as I've mentioned earlier, the series ended in a fantastic way and should be left alone for a long while.
Best wishes.
