Nearly every Sony 1st party game is like GOW. If you can't see it then maybe take the playstation glasses off and have a look. Having some different side quests and boss fights don't make a game different.
In the sense that their big AAA titles (Uc, GoW, TLoU, HZ, Ghost of Tsushima) all have stories and a third person camera?
Sure I guess, but there is no mistaking one for the other, they all play differently, all have different tones, etc. and none of them can be mistaken for another game from a different company either.
This is not like we could expect to see a new camera angle, or whatever at this point in gaming, maybe the looks will be different, some new game type on an existing style of game, but nothing will "revolutionize" gaming on a TV.
By your definition if they added mocap to the next Mario game it would become a Sony game (BTW, Sony has the best 3D Mario by a mile bundled with the PS5).
I'm not sure that is a real problem either, it only means that the media has matured, so people working on a game project, either alone or in a giant studio have a basic template set for them for almost every game type out there (puzzle, third person adventure, linear, open world, side scrolling, top down, isometric view, fps, violent, non violent, without or without ennemies, mystery adventure, whimsical, gritty, pixel art to 8K, grounded or out there setting, sci-fi/fantastic vs realistic, puzzle, so on and so forth, elastic controls vs twitchy controls too).
Even the things that feel fresh these days have some kind of precedent for at the very least a good portion of what's being done.
