Well i dont disagree with rinnegan but the wood release seems more possible than it.Its gonna be Rinnengan. Sasuke already has indra's power and the only way I can see Sasuke being pure yin is if there is another level of PS and gains access to the spirit weapons + a new one (there are three regalia not just two: totsuka, yata no kagami, and yasakani magatama)
you got a good point.I would have prefered the Indra eyes. Rinnegan and Mokuton make him too unoriginal.
I could actually get behind this.Both naruto and sasuke is gonna get the rinnegan
