This could of been from a hack done years ago, milked for all entirity in secret and then released years later. Alot of passwords would still be the same, people habitualy if not controlled to change there passwords every N days will not bother unless some event dictates thay should and then if they can avoid it then alot will sadly. Sadly the human finger fits perfectly into the human ear and this is how alot of people handle alot of problems. Now that all said if you look at any password system you will find common passwords and if you allow your user to use things like football teams, there own username and words like "god" "jesus" etc then you will get a standard statistical spread. The only conclusion you can make is if you get a million needles and chuck them in the air and do it twice that in pile A and pile B you will find some that point north, its the way it goes. So what does sony and yahoo have in common - passwords picked by humans, used by humans - just like alot of password systems, be they hashed, tripple hashed or plain old text.
