It won’t cost that much, because most people wouldn’t pay that much. Economics.
And people paid $250 for it in 1993.
But it’s not 1993. Premium home entertainment is no longer a niche market. There certainly would be people buying it at $250 plus today, but they would make more money selling more at a lower price. In 1993, you already had to have money to have laserdisc, but BD is a format for the relative masses.
BD is as cheap as dvd.
Which is why I’m honestly a bit shocked when I walk into a Best Buy and they’re selling $25 DVD players next to $40 base model Blu Ray players. Who’s buying them?
