This is great news...

Sony will make it such that developing 'DRM' software will be unprofitable - or at least, no company in their right mind would be willing to license to Sony or to any other litigious RIAA cardholding member.

Sony would be forced to develop something in-house or have to work with operating system vendors, such as Microsoft, to develop a next-version OS which no one will want because of it's in-built cripple-ware.

With luck, everyone will abandon the whole sorry mess and everything would revert to the "Innocent until proven guilty" honor system. Like as like not, people who intend to pirate music would do so regardless of any technical limitation imposed upon them as they will find a workaround. The rest of us, the majority of people, don't pirate music and don't appreciate being treated as if we were already assumed to be criminals.
