I personally don't get the "keep it for myself and my talented friends" mentality in this scene. When the lv0 keys were leaked, a pis$ed off Kakarotoks said he had them for a while, but never wanting them to see the light of day, why??? If someone can bring something new to the table why not release it (even if you want to wait a while for testing and so on) so that more people can enjoy all the posibilities of a jailbroken Ps3?
Anyway, all I can say is that I have complete faith in this person (who confirmed the CFW, not the actual dev)and he's been around for a long time.
All we can do as always, is wait n see and hopefully those 3K+ conoles and their owners will have a merry christmas
