Isnt there an issue with "Buy" and different countries marketing laws? Ie it implies "Hold" or "TemporaryKeep".

Guess it will be an upswing of BlueRay movies. Already happening with LPs and CDs

This anti-consumer stuff also applies to physical Blu-rays: each BD can contain a revocation list of player keys and distributor keys, and official players are required to update their keylists from that. Every time you insert a new disc in your player, you're playing russian roulette with your existing library.

How does that work if my player is offline? A dedicated BluRay player has no reason to connect to the internet.

Each disc contains the latest revocation list at the time of its creation. If you put in a disc with a newer revocation list, your player updates. Same thing was done on the Nintendo Wii.

Blu-Ray key revocation does not work that way. Players with revoked keys simply can't play discs that were encrypted to disallow them.

Discs that worked with a player will continue to work, as long as the physical mechanisms are still good.

Technically, maybe, since the player authenticates with the drive, if you updated the firmware on the drive you could lockout the player. I could see windows update potentially helpfully pushing a bd-rom drive firmware update, but it's not happening on a standalone player.

It's not ideal that your existing player might not read new discs, but hopefully you use your discs soon after purchase and you could return them if you can't get a firmware update with a new key. (Of course, I'm guilty of buying discs to watch eventually; will be annoying if my keys were revoked)
