afterall in gaiden sasuke still needs MS/EMS in order to use susanoo, so the "perfect/complete susanoo grants eyeless-susanoo" doesnt work... Until we get more information, it's pretty much a fact. The only one to use Eyeless Susanoo was Madara, and he had a Perfect one. I could say there's a stage beyond Perfect, namely Eyeless, but IMHO that defeats the point of naming it "perfect" or "complete" susanoo.

Gaiden raised a lot of questions and "why Sasuke doesn't have eyeless" is quite frankly on the low end of Gaiden's big problems. Including that it introduced the concept that the Mangekyou needs to recharge at all.
