The launch window was a huge factor with so many big titles released this holiday. Fallout 4 especially affected it big time in my opinion. I know for sure now that the reason Sony delayed Uncharted 4 was to avoid possible low sales and maximize on the spring 2016 smaller line up. Of course they're gonna say it was to polish the game but I believe the move was very strategic.
