GamesIndustry.biz via Eurogamer: "There's absolutely no question but that this is a hugely damaging blow to Sony, and to the PlayStation in particular. The PS3 has already faced fairly significant market challenges, not least of which is the clear inferiority of the PSN services in comparison to Microsoft's more functional and widely-used Xbox Live services.
Clawing back the one-year sales lead enjoyed by Microsoft has been a tough task, arguably exacerbated by the technical and economical problems created by the PS3's over-ambitious yet poorly considered hardware design. This week's scandal shoves a stick into the spokes of that effort to best Microsoft's market position.
Even if the actual damage caused by this intrusion is minimal - and there's some suggestion that it was designed to embarrass Sony rather than to actually steal customer data, being a revenge attack of sorts for Sony's recent legal and technical attempts to prevent the opening up of the PS3 to homebrew code- the reputation damage is incalculable."
