Following he win Ioka has stated that his intention is to return in April or May and that he is targeting unification bouts.
At the moment it'd be difficult to see which champion he was hoping to unify against. It seems highly unlikely that he would be seeking a fight with WBC champion Roman Gonzalez whilst WBO/WBA "super" champion Juan Francisco Estrada would likely require a large payment to leave Mexico.
That only really leaves one option, IBF champion Amnat Ruenroeng, who already holds a win against Ioka. The bout would be a good rematch and would see Ioka getting a chance to avenge his sole defeat whilst Amnat would get the chance to showcase himself against a man who clearly developed into a better fighter than the one he beat back in 2014.
Whilst Ioka has stated his intentions it could easier said than done and we may, sadly, see him defending his title against a second rate challenger in his first bout of 2016 with the build up being for a big one in December, in his next New Year's Eve bout.
