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)
