My guess is that they want to release at least one version of the game by the time the original hits its 20th anniversary. But in order to make this happen, they will concentrate on one version at a time, instead of spreading production teams over multiple platform versions.
So PS4 version gets to release first, in time for the original's 20th anniversary, then they'll work on porting the game to other platforms.
