Utatane Piko is an amazing voice bank and has absolutely ZERO reason to be discontinued. Even if he wasn't the most popular before, his popularity has SKYROCKETED lately and would definitely sell today. Also, he has lots of fans who would be overjoyed if new voice banks came out or if his old one got rereleased.

It saddens many vocaloid fans that one of their favorite voicebanks got discontinued since he had such potential.

Piko is currently at the peak of his popularity so if he were to get undiscontinued then there is no doubt that his voicebank(s) would be a hit.
