and you fail to realize that Itachi was holding back, not even putting time control on it.. and Sasuke had to boost his Sharingan with CS2(CS2 is Sage Transformation which is Senjutsu.. basically the same thing as Sage Mode as the page itself shows) So no, a normal Sharingan can NOT break out. Obito made it clear the whole fight Itachi was holding back, and controlling it while Sasuke was going all out. I really don't understand how some people don't comprehend this yet...
