Blu-ray's adoption of DRM is being speculated as a protection policy for future PS3 releases, but the AfterDawn crew doesn't think that the copy protection policy will actually help much:

"But will any protection be enough to prevent piracy? I personally doubt it. For decades more and more advanced protections have been developed, and later cracked. MOD chips circumvented PS1, PS2 and Xbox protections, so why couldn't they do it in the future as well? On the other hand the Blu-ray format itself may slow down piracy at first, until the recorders get more popular and cheaper."
