With all the bounties available now, don't bet on a public release of a jailbreak but if a group like pangu is going to put one out there, 10.1 is when I'd expect it. I'd heard somewhere most of the players have met with Apple, not sure what the outcome or direction of that was however. There are still a few tweaks which are invaluable to those accustomed to jailbreaking, I for one can't live without Action Menu.
