New David interview. David puts the ball in Richie's court and says until he is great again. Seems to think that this will past and all will be good again:

Kevin Coffey: Do you know when Richie Sambora might rejoin the band?

David Bryan: I don’t know. The ball’s still in his court. Until he’s all great and helping us out, I don’t know.

There’s trials and tribulations in a band. This too shall pass. Everything will be good.
