So this whole thing was about those special eyes?

And the way they have been displayed so far have all been non-Awakened versions... Why does Imu desire them, what could he possibly gain from them?
And what are they like when Awakened?!
The only remaining World's Strongest has special eyes and his destined challenger keeps an eye closed since post-TS...
What is Oda cooking here? Is Imu trying to obtain eyes like Mihawk's??
