No, this is not the end of the situation. What this is though, is ammunition if a hack ever comes out on the ps3 again. There's not many really smart hackers out there who can hack the ps3, and this is at least a few of them. This will cut down on the number of hackers in the future, because if one of these guys ever hacks it again, their ass will be in jail.
Hopefully this is the START of putting things back together on the ps3 and will be enough to scare other would-be hackers away (legal action).
