the reason announcing it early is so that they can get feedback on the game and fix the issue that general audience had with the vertical slice.. it helped with spiderman and horizon..
So far announcing a game and releasing the game within a year has back fired, happened with Uncharted 3.. shooting mechanics, Beyond two souls, little big planet 3,
Right now even with Days Gone, so many people are having issue that its too much zombie, its last of us this and that. Same with Dreams infact that game probably went into redevelopment from scratch after people didnt understand what exactly the game is. So these feedback are essential for the developers to tweak and fix their game, and it cant be fixed within a year.
