IMHO don't think anything was compromised, SONY is just doing basic crisis management:
Blowing up the fact, so the truth will sound better.
That is not how that works. Crisis 101 is that you tell the truth, and if you don't know something certain you say that you don't know something certain.
In this case that means leaving open the option that CC information was obtained.
It really is stupid to say things are worse then they are on purpose to make reality look better. But is a death sin to say something is better than you know it is.
