The XB1 hack was not released and I doubt the X360 hack will be released if/when it's completed. From what I've seen, TS isn't really in it for fame/profit. He seems to be into it for the challenge of making the system do something that it's not supposed to do, which is what hacking was really all about in the first place. If/when the team gets it going, I'll be one of the people to say, Congratulations guys.
I'd love to have my system modded so that I can backup my games and have some peace of mind, but if they choose not to release it because of the personal (legal) implications it could have on him and his team then we should all respect that. I'm in the processing of learning assembly now, not sure how fruitful it will be but I'm gonna give it a whirl. If I or someone duplicates their findings (assuming they complete it) then it's up to that person whether they want to let it into the wild.
As far as unsigned code goes, who knows when we're going to get there, all we have now is speculation and an impending firmware hack, which is NOT going to magically emulate MS's private key. Again, I'd really LOVE to have my system modded to this end, but If someone gets there first and chooses to not release it due to their own reasons then so be it. None of the people who do this in their spare time, for their own reasons OWES us anything. If they choose to release their work, that's at their discretion.
