Witcher 4 isn't expected until 2027/28 at the earliest. We might see GTA 6 this year ... on console, but rumours remain strong that it may get pushed into next year.Haha, I know, but who said PC?
Also if neither of those are released (I did caveat that point by the way), there are still plenty of AAA games due for release that might be bigger more mainstream contenders.
