If Sony is admitting that they are going to be sending out emails about this, be wary of phishing attempts as this would be a perfect opportunity for the hackers (since Sony has admitted they have your email address) to take advantage of. Companies will never ask for things like account details or "verifying account" through personal information, passwords, CC numbers unsolicited through email.
