And I think it will take quite a while before he gets it, cuz that's the ultimate uchiha move and I think he only will get to now it when he gets as strong as Itachi(if that ever happens that is)
Didn't Kakashi say that if Sasuke gave into the cursed seal that his development ends there. Maybe he'll never be able to get it. I just wonder what the seal actually does to people's abilities.
We don't know the nature of Sasuke's Lv2 Cursed Seal yet, but the whole premise of beating Itachi would require some method to counter, resist, or avoid Itachi's Tsukiyomi, a cheap instant-win ability. It was never said that the one actually needs Mangekyo Sharingan to win; Itachi merely said that only someone with Sharingan can actually put up some resistance. Of course, we saw how well both Kakashi and Sasuke fared, so no matter how much power the Lv2 Cursed Seal gives Sasuke, it most likely won't be more than the power Orochimaru had and therefore still won't stand a chance unless it forcefully awakens Mangekyo Sharingan.
