I agree with this. It's highly unlikely that the first guy to encounter "PS3-related identity theft" just happens to have a credit card which was only used on the PlayStation Network (and is therefore proof against theft from another site). There are a lot more data points needed before any conclusions can be inferred.
Going back to the links in the OP, I have a question: Didn't Sony make mention that it never asked for CVV info, and thus had none to store? I thought it was weird that they'd brag about not using a security feature; but if they didn't actually use it, then the CVV info allegedly being sold is either fake or originates from a source other than PSN.
