Well by now we should all be accustomed to carrots being dangled in front of us... the last few have come with constant "almost there" posts that never come to fruition, so I don't think this is anything different.
On the flip side, maybe this was all just a diversionary tactic to save face. I know it won't be a popular comment, but did you ever stop to think that maybe it's finally been acknowledged that the iPad 2 at current firmware might not be able to be jailbroken fully, and by creating a leak, it gives the creator an out to say "fu@k it, I'm done" giving the appearance that they are leaving the position in disgust, masking the reality that they're leaving in failure to be able to find a successful way to beat the system?
Ok queue the fanboys and haters...
