I'm thinking that after these 2.5 years of training, a lot more of his potential will have been released, and the cursed seal taking out a little more will have less and less of an efffect. Remember how it says it forcefully takes out your chakra? Well if Sasuke is that much more skilled, than he won't NEED to have something force it out, he'll be able to take it out manually. And the tiny bit that IS left over unused might be able to be used by the CS, but probably won't be all that much anyway. So do you guys think that the CS is more for inexperienced nins who can't yet release all their power but could use the boost? 2 things bother me about this though. If Sasuke DOES use it and it DOES give him that much of a power boost, how much has he really grown all this time? Either that or I'm misunderstanding the mechanics of the CS and someone will correct me in the first post. Either way, I don't want to see any more kyubbi OR CS in the story. (Maybe a little kyuubi when it needs to be extracted and maybe it fights back, that would be cool imo) Thoughts?
