Sounds like Jon is in a creative place and wants to see Savatage go out with the best music he can do. I found it interesting that he said he has so much material, but hasn't decided quite yet if this is the last, or if another will come later. I think it likely will depend on how the new album and tour is received. The festival circuit is going to get a lot of the love. Hope a regular tour is possible.
Jon has been through a lot in his life in regard to personal tragedy. We all go through a lot. But man, that poor guy. I could understand him feeling like it's time to do this the right way, instead of keep waiting.
Looking forward to the new music and live performances. Really glad he and Zak will be singing together and separately throughout the new album. Love that dynamic.
