Personally I think that a lot of questions can be at least partially answered by the size of the team that handles the OS. I don't think the OS dev teams are that big compared to what you have in more dedicated OS business (Windows, Android etc.), so it takes longer to do anything. Typically the OS hasn't been a very important part of a console, and I don't think all console companies have yet switched the focus to the OS as much as they possibly should have.
