Worrying and a sad state the show has become to quickly. Alas, with confirmation there is no reunion I also fear a very heavy retooling of the show if not outright cancellation. Given the circumstances now and while I honestly liked all the cast as, I'd suggest some aggressive recasting without throwing away the entire show legacy.
NEW HOUSEWIVE (make it someone known and notorious)
Friends Of - Sonja, Eboni, Elyse
I feel Bethenny and Dorinda can reposition the dynamics as quite the firm power couple. We need a PR event to some degree so bring in Jill at last and top it off with a new Housewive that is known for some extra punch. Eboni will just need to go, we can't have the show go off for another year in the direction it was dragged but she'd be a nice FoH.
Sonja can function fine as a FoH, there's nothing else she can bring that we haven't got a million times before.
