it seems to me that yes the rinengan is the ultimate eyes, hands down. but is it the final version?... i say this because im really big on symbolism, especailly the past 5-6 chapters been giving me a whole lot of symbols ...
for example when kurama has a flashback we see the back of the sages cloak it has the rinengan and 9 tomoes .. this leads me to think but not to assume that the final version is the rinnengan... but also with 9 tomoes just as the juubi had, some even specualte that the s06p gained the rinengan only after he became the host of the jubbi. but thats another topic.
