Well your ass is right :P
I agree, it didnt really catch on like from VHS to DVD because it was really just a 'upgraded' version of a DVD. But despite the not-so-huge impact it made, blu-ray it's now the physical standard in every household for movies and home consoles games so I wonder if that's enough of a win for Sony and others in the blu-ray party. But now its just been a tough battle between physical and digital lol.
In my household we bought several Blu Ray movies in the beginning but after maybe the first year, streaming/digital was just too convenient. If not for the digital era, things would definitely be different. I just wish digital had the same extras that physical media has.
