"Every jutsu has a weakness." - Itachi
The question is finding it. As far as we know, Sasuke's teleportation jutsu is virtually just Hiraishin without the kunai. And as we all know, Minato was so feared that entire platoons were told to retreat on sight of him. Given this fact, Sasuke is currently unstoppable. Kishi never really did give a counter for FTG (other than using a technique that latches on to the FTG user when Obito's mini bijuu bomb stuck to Minato's arm), so if there isn't a counter for FTG, then there isn't a counter for Sasuke's S/T jutsu, only limits. And even if something is outside his range, all he has to do is lock onto something (for example, Sakura's flak jacket) and problem solved.
Personally I don't like all the wanking of Sasuke's S/T jutsu, but mangaphax and logic are on his side at the moment.
