And it all comes down to Dragonball Z, Super Sayajin-Mode...
Well, if you want to find signs for Zoro having the Haoushoku, you will definitely find them. Since Sovereign-Haki means people have problems to stay calm and concious while standing near people who possess that power, that has been obviously from the very beginning. But frankly: who cares? I really don't see the purpose of that power. Only those lose conciousness who are weak anyway, so it doesn't really help when you fight someone really strong. Or does anyone expect Luffy, Zoro, Sanji, Nico Robin or even Nami to lose conciousness?
It is just a power to simply show off, if you ask me. And this "only one in a million is chosen to possess it"-thing, well, I remember Vegeta saying exactly that about Super-Sayajins (one Super-Sayajin in a 1000 years), until Son Gogu, Vegeta, Trunks, Son Gohan, Son Goten,... got it. And since it is safe to assume that about only one in a million become pirate to begin with, the whole crew might get it, and it would still be one in a million. And nobody would be surprised if Trafalgar Law, Marco the Phoenix, Diamond Jaws, Mihawk DuLacre had it.
And there is one thing: Why didn't Whitebeard use it when Ace was about to get killed? It's confirmed that Whitebeard possessed it (Ace as well, by the way, that enigma is even stranger!), yet he still didn't use it here?:

The usage of this power is random at best. The only reason for Haki to exist is to even the playing field when it comes to Logia-users. And that is what I like about this chapter: Zoro defeated an opponent just by demonstrating that he could kill her anytime, but without hurting her. That's something only he can do. Not Luffy, and certainly not Sanji.
