oh and thats why he said "pure chakra... he threw me all that way with chakra" and not "uh he got more skilled, he saw through my sneak attack" :P
no no this wasn't a sneak attack at all
sneak attacks in naruto-verse are normally made very fast with one swift movement and not with thundering, yet slow, footsteps
and yes we've seen him taking more dmg, that happened when he wasn't prepared to get hit... this time however he got hit even harder but took less dmg maybe he was PREPARED to get hit? maybeee?? maybeeee? xD
ah well lets just wait one week maybe we'll see more then and can have a new argument! ^^
