So the advanced versions/upgrades for each haki is:
Armament haki > internal destruction
Observation haki > future sight
I'm a bit confused with the advanced Conquerers - all the translations during the Kaido fight at the time seemed to suggest that Luffy being able to hit him without touching was to do with Conquerers, but now I'm seeing that was actually Armament's "emission", and the Conquerers part was just making his attacks stronger, called "infusion"? Nothing about Armament haki was even mentioned during pic related! The title of the chapter was even "Conquerer's haki".
