Estrada just announced that he was moving to bantamweight, so that's probably not going to happen. But to answer your question, yeah... and one that hopefully Pumita brutally pushes his **** in.
Fernando Martinez is scheduled to fight Ioka again at the end of the year. If he manages to beat Ioka again then we could see him and Bam face off against each other next year. That would be a full on barnburner at 115. I don't see Ioka having much of a chance in the rematch but if he manages to avenge his loss then it would be nice to see him go up against Estrada or Bam.
Martinez is rumored for an Ioka rematch which means its at NYE this year following the trend, so more like June/July I'm expecting if it is Bam next.
