Minato fans are in for a reality-check next chapter. The Hokages are additional support for an already existing army against just Madara and the Jūbi at this point, with Hashirama being by far the strongest among them and the one that will garner the most attention and praise from Madara.
That was Minato's golden moment, and it doesn't really change his ranking, least of all how he matches up against Itachi. If you're particularly unlucky, which your hubris is teasing fate for, then Minato will hype Itachi or be hurt/humiliated as a reason for Naruto to tap into his power through rage.
