"Anyone think BluRay will go the same route?"
Yes. BluRay is already an obsolete technology. Look at music technology. We don't use CD's anymore, we have ipods, or other devices. Same thing can already be done with video. Those small little usb flash drives for example. Make it an hdmi flash drive, put movies on it, and plug into smart tv's. Bam you got your movie.
The industry won't bother moving in this direction until they have their run with bluray. For me, I burned all my dvd's to a external hard drive, but since the industry won't make a sort of player that you can just plug in the external drive, and hit play, I have to use a backdoor method of running an hdmi from my computer to my TV, and use my computer as the player. Its worth it in the amount of space now saved.
