Personally i dont think PS4 will be released for a very long time, but at that time i think Sony couldve already developed the next format after blu ray, and blu ray will already be very cheap to implement into devices, like DVD is now. so i can see nintendo or microsoft using blu ray at that point.
or they could develop a higher standard of blu ray. and just keep using that. the problem with digital downloads is that not everyone has a broadband conection, not everyone has an internet connection (i would assume), especially in the emerging markets.
