Hi there

. You seem to have missed my point, I believe that Sasuke had the transplant done under the impression that he was receiving Itachi's Eyes. But Madara tricked him and inplanted the Rinnegan instead.
Urahara is awesome

my favorite character in Bleach.
Yes, he told Madara that he wanted Itachi's Eyes... Doesnt mean that Madara actually inplanted Itachi's eyes into Sasuke, though

.
Well, we don't know for sure whether or not you can actually tell the difference between eyes in the Narutoverse... I mean, Madara could have transplanted eyes from some random hobo into sasuke, and since Sasuke thought they were Itachi's eyes as he had requested, he made that comment "I feel itachi's power flowing through me." when he actually felt nothing... The phrase was used for more dramatic purposes more than anything else.
It is possible that Madara has plans for Sasuke's EMS, but I would think that he would rather have the origination of both the Sharingan and The Rinnegan (as pictured in the drawing of the Juubi), Having the powers of both, and perhaps some new ones on top of that.
That was the whole point of my theory

lol.
which brings me to a part of my original theory that got deleted before I could post it: I believe that Itachi intentionally abused his Sharingan in his match vs. Sasuke for the sole purpose of going blind. He accomplished this, and therefore I think his eyes are
useless..
It is my understanding that the purpose of transplanting a mangekyou sharingan was to obtain "new light". Now, how can there be New Light if the eyes being transplanted are already blind? Sasuke Exchanging his own blind eyes for Itachi's blind eyes= new vision? doesnt make sense... 2 wrongs= right? I don't think so.
Plus, I don't think that Madara saying this:

so shortly before transplanting "Itachi's" eyes into Sasuke is a coincidence..
