There is the expectation that we have on the information that's being spread but still, the official one is still the best source that we can ever know when it will happen.
If the announcement will be delayed, we cannot expect a fight to happen this year.
Donaire is already in good promotion management now, same with Casimero, so they have to win against their challenger and start next year hunting big fights where most likely either one of them will get Inoue, but I have a feeling Inoue will choose an easy path which is Donaire since he beat him before.
Then that would be by December and there's still enough time for them to market the match and for sure that it will be easier for them. Because there are a lot of fans that are waiting to watch some good boxing matches and this match of Nonito is included and worth the wait.
I think Nonito keeps his body active after his win against Ouballi.
And the order was released on September 21, so maybe after both parties received the order from WBC they might have have prepared themselves for this fight already.
For the promotion, again a full one month could have been enough for this fight. And the one handling this fight have many experience in promoting a fight so I don't think this will be a problem.
