Sony so far hasn't announced any games over 2 years before their release this gen, I can see Death Stranding being one such title, mostly cause it was a special case where they just wanted to brag about getting Kojima on their side.
Other than that I think Sony's pretty conscious about not announcing stuff too early, likely a due to The Last Guardian debacle. They mostly seem to be waiting until they have gameplay to reveal most of their games like Horizon, God of War, Days Gone, Dreams, Spiderman all debuted with gameplay demos or atleast videos of gameplay. They've mostly stopped revealing games with CGI trailers, the only one I can recall was Bloodborne and for that they showed gameplay 2 months later at gamescom.

So yeah I see no reason to believe these games have been revealed too early barring something going wrong with their development.
