Zoro fans shouldn't be too excited about this; it's obviously something Oda will use to hold Zoro back again very soon. All Zoro ever gets is 'implications' but when it comes to actual fighting, it's guaranteed something will be put in place just to allow condom to outshine him. That has been the case since Arlong; it was essentially spelled out for us that if Zoro was at 100% Arlong would be dead meat, according to Arlong himself, but people omit the implication and only focus on what was drawn, i.e. Arlong holding a 'defeated' Zoro by the neck, until big panchi man eventually comes to the rescue.
Just hope for the best when it comes to Zoro vs Mihawk, because in reality that's the only whing we have that won't involve Zoro getting outshined.
