Blu-Ray is a corpse.
It even didn't take over as a proper profitable medium for movies.
Since you watch a movie only once or twice in a lifetime, it doesn't make sense having the physical product.
WEB-DLs smashed Blu-Ray.
CD is still very useful for music archiving though (and playing).
And this is my last opinion on this, gonna stop to bite the bait... back to "Not The Actual Events"!
