A new album every 5 years does not seem crazy to me. Tours would be limited, of course, to something like only 50 shows per tour. Even so, the brand would continue to live. Even though Jon no longer has a voice, the guy takes care of himself and he is healthy. Look Ozzy, he's still making records. I'm sure Jon will continue to make music, and he will use his brand, he will move on as Bruce Springsteen or Dylan or U2.

A release every 5 years, would be 3 albums, it is completely feasible. About the rest of the band, well, by continuing without Richie, it shows that official members don't matter. So Tico and Dave can be easily replaceable when they decide to stop.

As you have said many times, BON JOVI was always Jon's journey. That is why we will never have a JBJ solo album again.
