So I was just watching another Kiske interview on youtube, and the guy asked him if there were plans to do another Unisonic album.
Kiske mentioned that before the Pumpkins United was happening, they were starting to put plans together to make a third album, but that Kai was constantly off doing other things like his Hansen & Friends and reissuing some Gamma Ray stuff.
So they approached Gus G, and he initially said he'd do it, and they even started exchanging ideas. He was playing with Ozzy at the time, but pulled out because he didn't want to be a replacement guitarist in another band. He would end up leaving Ozzy's band and he came back to the Unisonic guys, but by that time, the Helloween reunion was underway. A blown chance..
