Probably none at all. Sony is still one of the biggest investors in the Blu-Ray disc. Chances are, the fact that they didn't include a HD BD drive in the PS4 Pro is because they know that the format isn't selling nearly as well as it used to, and simply, isn't worth the higher costs. The fact is that streaming has become the far more popular option for viewing film and TV shows, and very few people actually buy physical copies nowadays. Sony opting to focus on 4K streaming is the far smarter move, and it's going to pay off for them. As for the future of Blu-Ray, outside of being a format for games, it's probably going to become more and more scarce until it eventually goes the way of VHS.
