I miss the option of "they should have taken a long break after The Circle", which would have lead to a new (and final) era, like Crush did. But since that is not an option, I said not yet.

However, if Richie is gone for good and Jon decides to continue releasing Bon Jovi albums and touring with Phil X, then it's the time. But I don't think he will. For me, I just don't see Jon contiuing the band until Richie returns, other than filling the obligations to do shows, which is what he's doing now. If Richie doesn't return, I guess Jon will just start putting records under the "Jon Bon Jovi", which will sell a bit less, but nobody will have a problem with him ruining the band's legacy.
