First off, you don't seem to understand at all the nature of vinyl records as compared to other, newer forms of physical media. CD's, DVD's etc. are definitely not "coming back", simply because they don't offer anything that streaming and dowloading services in the internet could not do. Vinyls on the other hand do: they are extremely durable compared to newer disc-types(very few cd's can survive for multiple decades, even if kept really well), and their sound quality is better than in digital media, at least according to music collecting autists, who are the main niche group that buys vinyls. Huge stacks of vinyls are also impressive looking and can be used as stylish decoration element, unlike smaller discs. Vinyls are items you buy to not only get the music, but also the lifestyle that comes with it.
And why would streaming services die? If something they will likely become just bigger, and eventually will come to dominate the entire mainstream media field, as there is really nothing to stop them doing so. Only thing that could really "burst the bubble" is that pirate streaming sites would become so huge that it wouldn't be profitable to run companies like Netflix anymore, but yeah, I'm not seeing that happening.
