Bambusek, thats a valid point. I was thinking the Uchiha have an Uzumaki counterpart. I mean, all it would take somewhere down the line for an Uchiha to not have activated their sharingan and go "Screw the Uchiha. I don't need the Sharingan." and start their own clan. Greatest Sin, I believe the cycle restarts about a year or so after both incarnations are dead.
