Hansi "leaving" D&W is just a formal way to put it. The band was him and Jon and there is no sense whatsoever for Jon to do another D&W album with a different singer.
A longtime friendship built upon music and touring together, two albums, 15 damn years to wait for a new tour and a new album, and when we finally get new stuff, Jon goes full conspiracy mode and becomes a domestic terrorist. Meh. What a sad, sad end for such a cool project and great musical partnership, and I can't even imagine what it's like for Hansi to see a friend throw his carrer and life down the drain.
BTW, Iced Earth is doomed the same, we just don't know it yet... I assume the other guys in the band are waiting for a formal sentencing of Jon to announce what to do.
