So Dio has confirmed this. There will be a Heaven And Hell studio album. That is absolutely killer! I'm actually surprised at this, as Dio's stance on the issue has changed since it was first brought up before the tour. They must be having a great time out there, getting along and everything, to get Dio to put his solo stuff on hold. He was adamant before about not doing a studio album.
Could be they're being offered a ton of money, too.
