Maybe it would depend on whether Jon could be happy performing solo at smaller venues or if the lure of playing the big stadiums in front of thousands is the stronger pull. I think he'll always feel the need to perform, but can he be happy with just his "side job" to fulfill him, instead of his main job he's held for 30 years. My bet is ego (more so than the money side of it) would win out and he'd push for another full blown band tour.
