No, you are correct. The three tamoe sharingan can predict movement based on muscle twitches.

@ darkshadow

Byakugan has better insight? Are far as I can see the only abilities of Byakugan are these: see far away, see through things, see almost 360 degrees, and see chakra movement/tenketsu. As far as thats concerned, Byakugan has better sight than insight. In no way can it predict movement, that all depends on the user's ability (which I must say Neji is quite adept in). However Sharingan can; how else would it be able to copy jutsu fast enough?
