As I understand it Stefan has no plans to release the Phont and Superbra catalog digitally but who knows in the future.
As for Primevil I can't see that ever happening essentially after the collapse of all things Prime related they gave everyone there rights to there music back. So if that stuff is to see the light of day digitally it will be the individual artists who do it and not Primevil.
oh well looks like the only way is get them is buy the vinyl an rip them what a pain
