Yeah, pretty much confirmed for me, that zoro will get his time hiyori and orochi + his background will be revealed here.
Ps. I believe hiyori is in onigashima, there was in the last chapter a woman, who played the same instrument as hiyori. So I believe she infiltrated onigashima to kill orochi herself.
She purposedly didn't say anything to the others, so that they wouldn't stop her. But things will get fucked up, so zoro will come to the rescue.
My theory on this.

I think you are right on this. Hiyori disappeared days before they even set sail to Onigashima. It'd be very uncharacteristic of Oda to just let main arc characters hang like this. Its very likely this is her and she will try and assassinate Orochi. I wouldn't be surprised if she is wearing a mask again here (and people don't recognize it because they believe she is dead). Though Orochi knows she lives so maybe he's just letting her play here (she'll likely fail in assassinating him).
