Been a lot of discussion about how Uzumakis are Senjus.. but I don't think this is true. If we take the time to compare what is known about the Uzumaki and what is known about the Gedo Mazo there are some strong similarities between them.
Uzumaki (human descendants of the body of the Juubi)-
Creates chakra chains that are strong enough to imprison a tailed beast.
Kushina survived tailed beast extraction (all the other hosts immediately died after extraction).
Karin can heal mortal wounds by allowing someone to siphon her chakra.
Uzumaki's were long regarded as being sealing masters
Uzumaki's were known to be perfect containers for sealing tailed beasts. We've seen other lineages cannot successfully contain a tailed beast.
Gedo Mazo (actual body of the Juubi)
Creates chakra chains that are strong enough to imprison a tailed beast.
Gedo Mazo survived tailed beast extraction.
Madara survived a mortal wound/old age by siphoning gedo mazo chakra.
Gedo Mazo is a container for sealing the tailed beasts.
If we consider that the Uzumaki lineage is actual independent of the Senju or Uchia we'd get this..
Senju = Body of the sage
Uchia = Eyes of the sage
Uzumaki = body of the Juubi
So now... If we have have called out these 3, what clan could represent the eyes of the Juubi?
Ah yes, the Hyuga
So where does that leave us on Naruto himself.. I think Naruto is actually a descendant of at least 3 of the 4 clans.
How could this be?
Kushina
Well we obviously know that she's an Uzumaki.
Minato
Not much known here, at this point in the manga there isn't much point into keeping his lineage a secret unless its to shock us with something new.
So let's assume that Tsunade is Minato's mom. She's got blonde hair and she's a Senju, we know she was hooking up with Dan Kato who we also don't know much about, but he does have the ability to share chakra with others as he restored Tsunade. Let's assume he's at least part Uchia.
Naruto
So going off these assumptions, then Naruto himself would be a combination of the Uzumaki/Senju/Uchia bloodlines, and he also has a Hyuga girl that is definitely into him.
So if Naruto and Hinata have a kid it would signify the unification of all the former bloodlines, and the true return of the sage of the six paths.
