The Old Zangetsu that Ichigo saw was actually his Quincy part. Hollow=Poisonous for Quincy.Shinigami kill Quincy. Therefore the Quincy part of him started suppressing Ichgo's real power as being a Quincy he would have to kill Ichigo. But now Old Zangetsu has left Ichigo with only his hollow and Shinigami powers. It would be cool to see what Ichigo's Shinigami powers would be after knowing that all his strenght was mostly due to the Hollow, even his Getsuga Tenshou resembles a Cero(said by Ulquiorra)
