yeah, i think so. he may open the eyes and say "bankai" or " Sharingan"
one piece 666 may show us the truth
zoro?s eye is closed .but i don't think he is blind ,i guess if he's eye open,he will be more stronger .
If it came true, it will be a good thing. but i am not care this. do not you think the scar on his eye is more awesome? !
btw, i think the most attractive man in the one piece manga is zoro.
