Its the credit card company's time to shine now. Catching the fraudulent purchases is one thing they can do for the people now.
For the people buying the stolen credit card info, I really think that they will end up being victims in this as well. The fraudulent purchases can obviously be tracked, and some lucky law enforcement will be booking some people for having these numbers.
All in all, not too worried about my meager debit card funds. I'm down into the single digits as far as dollars go in that account, and I'll keep it like that for awhile.
I think Sony will improve on their system, maybe even make a couple of security enhancement for their NGP. They have time though, the PS3 has some staying power. But until then, I wanna see my PSN back.
