Wow, this is awesome news. I think it's is a complete pick em honestly, largely depends on how Rigondeaux handles the step up. I don't think either man has a stylistic advantage, they are both brilliant natural counter punchers so this could be a pretty edgy fight. I do think Rigo has looked more fluid or natural over the last couple of years, and while he hasn't fought anyone very good Donaire has also looked pretty complacent against a couple of lesser opponents. Really see it coming down to who wants it more and rises to the occasion, skillwise they are very near even to me.
