You may also notice, from the lines you bolded, that they used the words "possibility" and "may". Again, there is no evidence that credit card details have been stolen, and Sony are advising that you keep an eye on your bank/credit card accounts just in case.
It should also be noted that Sony do not store the 3-digit security code from the back of your card that is required by most places to authorise a purchase or payment.
Anything else you'd care to get wrong?
