Perhaps but in their history Sony have, if anything, been too shy about coming forward with data. For them to say passwords are compromised...well that's a massive red flag to me, it's PR's job to spin the best out of anything and for them to admit anything which is not positive is usually a pointer to VeryBadThings™. Consider any other data loss I can recall in any industry, the first thing they do (assuming it applies) is reassure everyone that the data is unusable/encrypted.
If the break in had resulted in the loss of a salted hash table, I'd be gobsmacked if it made the press release because it's not a realistic concern (if done properly). On top of that, there have been articles in the run up to this about weakness and vulnerabilities/poor practice going on at Sony, I don't have much faith in their security handling.
I agree, they are scant on the details/information but equally, they are alarmingly short of good news too. Any PR puppet worth a damn will shout an "upside"/"don't worry, nothing to fear" items of an event like this from the rooftops, they're not...so why not?
I appreciate that they may not know the scale of the intrusion and that's fine, indeed understandable, if these people were good. However, there are strong implications that the data was not encrypted/improperly stored in the communications. Were the information encrypted, even had it been broken later, I'd expect PR to say something like "Yes, there's been a theft, however all the data is encrypted at industry standard levels so the risk to consumers is minimal".
I would bet a sizable sum of money that once the dust settles we'll see Sony have either cut corners/been reckless in data security terms
