The following dissection is merely a hypothetical ramble based on my observations of the last chapter, which gave way for a heap of speculation regarding the path of Naruto and Sasuke in the future.
Naruto revelation
It is has now been revealed that Ashura, the younger son of the Sage, had his chakra transmigrate over time and in to Naruto as the current incarnation (as he did insinuate that it has happened before). This is another addition to the long line of parallels that encompass this manga. With this confirmation, we know Naruto has a lot more potential in the future power-wise, and he is the true successor to the Sage in his entirety.
Sasuke inevitability
It is basically a forgone conclusion due to the immense amount of parallelism that Sasuke will undoubtedly represent the incarnation (via transmigration) of Indra, the Elder son og the Sage. Again, what this does is confirm Sasuke’s potential for power is boundless and will definitely sky rocket even more in the immediate future.
Breaking of the parallel
We know Sasuke is gaining Hashirama’s DNA via Kabuto who is injecting it into his open wound while very “near death” akin to the way Madara awoke the Rinnegan. However, this is breaking the parallelism of Indra and Ashura, as they relied solely on what they were given (Eyes and Body) to fight each other. With Sasuke gaining Hashirama’s DNA, he has the potential for the Rinnegan (which is just as much a body power as it is an eye power), strong physical being (A trait of Ashura), the aptitude for Sage Mode (via Hashirama’s DNA AND Juugo’s DNA within him), the inevitable Perfect Susano’o and we know that the people who acquire Hashirama’s DNA gain Mokuton as a by-product, and judging by the amount being “pumped” in to Sasuke, it seems to be proportionated to Madara’s amount, and we know Madara was able to replicate Madara’s Mokuton to a tee. Even amongst all this, with Sage Mode, he can possibly access Shinsenjuu as Sennin Modo+Mokuton leads in to Shinsenjuu (showcased by Hashirama). What this does is break the known parallel between the sons and directly; Naruto and Sasuke. How will this be alleviated?

What Hagoromo will entrust
The source of Sasuke’s new incoming power is Yang and subsequently body related. Naruto just received Yin Kurama and the Bijuu’s chakra. Hagoromo will inevitably “entrust” something to Naruto, and it’s almost a guarantee it has to do with powering Naruto up. This is where the parallelism is both reformed and transcended into new heights. Sasuke will gain body related power to heighten his abilities, and Naruto will gain the Rinnegan, an eye related power entrusted to him by Hagoromo in order to take down Madara.
The Transcendent parallel
The beginning of Shinobi essentially dates back to Kaguya who had TWO sons born with chakra; Hagoromo and his unnamed (but in the near future, he may be named) brother. We know BOTH of them were born with the powers of their mother (albeit watered down considering Hagoromo’s description of her power and superiority to everyone) and BOTH of them sealed half the Juubi each within them. They are practically identical, albeit, Hagoromo seemed to be “less human” in appearance given his horn like protrusions while his brother, if Madara is any indication given his appearance as Juubi Jin, was a lot more “human” in appearance as he lacked the actual horns but rather had the head wear reminiscent of horns. This is also represented by Obito vs Madara as Jin given the stark difference in appearance. As for how Naruto and Sasuke “transcend” the initial parallel, it comes down to how they are the main characters and how they will inevitably be the most powerful (except Kaguya, as the Sage was “de-hyped” and now is admissible in being surpassed by present day Shinobi). Sasuke in gaining the “Body” and Rinnegan through those means is part of the Hagoromo brother -> Indra -> Madara -> Sasuke parallel dichotomy, and will achieve “Rikudou” status through more human means and his appearance won’t be altered that much. This is opposing Naruto, who will gain the “Eyes” (and watered down Juubi Jin mode) via the “beasts” much like Hagoromo’s method and he is part of the Hagoromo -> Ashura -> Hashirama -> Obito -> Naruto parallel dichotomy. In defeating Madara together, they will have done what the original sons of Hagoromo failed to do and that being to cooperate, but they will also parallel Hagoromo (Naruto) and his brother (Sasuke) in subduing and ridding the world of the Juubi once and for all.
