So....3 rounds eh? Since this doesn't seem like any sort of pivotal point in the series, I'd guess that...

round 1: luffy loses and zoro is taken by the foxy pirates
round 2: luffy wins and gets zoro back
round 3: luffy wins and takes foxy's pride

This would result in nothing changing with luffy's crew for good or for bad, and the bad guys lose.

Although then again, if this short saga does hold any relevance, maybe this could be the start of a bad chain reaction of events......
