I think sasuke will unlock a better version of the sharingan

[bigfatloser]

just think about it, itachi always bashed madara for stealing hashirama cells and unlocking the rinnegon. and the sharingan is awakened through loss. losing a close friend/brother unlocks MS, EMS is unlocked from a transplant so death with EMS probably unlocks GEMS, godly eternal mangkou sharingan. which look like 4D cubes in sasukes eyes.

what do you think about my theory

 

[Huzaifa]

For all we know sasuke can evolve into a chicken and solo madara. It depends on how high kishi is really.

The Elder Son's eyes or the Rinnegan is what Sasuke is going to awaken most likely.​

I say neither will happen.

I'd really like a 4 tomoe sharingan

I feel like that would be ugly.

Nope not possible, I don't see that coming
