I got Ninja Of War implying that anyone with skill can break Tsukuyomi, then I got ya'll implying no one can. You got me with nothing. I clearly said that I don't understand why it is assumed that Itachi has the authority to limit other shinobi. Then you cite two descriptions of the databook. One that says "Concurrently, no one can break out of Tsukuyomi without the sharingan and Kekkei genkai". I looked it up to make sure it was correct and that word is present.

So, using Your first version databook definition, "Concurrently" fits with the story-line playing up Itachi. "Concurrently" means as it stands now, and doesn't limit all shinobi's abilities. That's my point. So there is a chance, it's not iron-clad as you say.

There was a thread a while back that explained how the source of Tsukuyomi's strength was it's speed of time-dilation. I'll try to find that post and repost it here, as I think it will be helpful.
