It was my understanding, that the drive would continue working, but once a certain host certificate is revoked (the infos about revoked certificates are written on new Blu-ray Discs), this old certificate won't be accepted by the drive anymore. So you cannot playback old discs (unless you have stored the Volume ID elsewhere). A newer host certificate should be enough to perform again the authentication. Just as you can imagine Software A (e.g. WinDVD) uses an old host certificate. Then this HC gets revoked, and Software A cannot playback anymore on that drive. Software B (e.g. PowerDVD) has a different host certificate, and should play back BDs with the same drive just as before. And a software A' (e.g. a newer version of WinDVD with a new cert) should also be able to play again.

My thoughts about this could still be erroneous, as I didn't have a revoked certificate yet to test this theory.
