Simple logistics I'm guessing. Late February is not a good release date for anything not already scheduled. Horizon Zero Dawn is looking good and slotted for Feb 28, Nintendo Switch and Zelda is March 3rd, along with other Nintendo titles, and Mass Effect is late March. There really isn't any room in there for any game, regardless of quality. I don't believe it has anything to do with development.
I agree with this.
Take
Kingdoms of Amalur: Reckoning for an example. Great game....released around when
Skyrim came out. Guess which game got more attention?
They are probably putting it there so it's the only title in that release window that gets attention. Good move, imo.
