... Who?
What are you basing your claim off? Pangu?
This is what I have heard, correct me if I'm wrong: Pangu was a tool that used an exploit that was given to the Pangu team by i0nic (whether you love or hate him, I don't care). Pangu didn't find it, i0nic did. It was an exploit that would have caused legal trouble for Americans to use.
So... What makes you think that the Pangu team is gonna find the next jailbreak? They didn't even find the one they used for 7.1.0, they learned about it in a seminar class.
