I think the urban gospel, or any other format idea, is dead. There's no reason to take 3 months, especially considering that Summit has done several format changes in other markets. If X is doing that badly, it seems like they'd have ditched it by now. I think sticking with the X format is a safer move than a lot of riskier stuff they could try. Maybe that's the reason?
Maybe X will be able to stick around long enough until the cluster is (potentially?) sold and be saved? That'd be ironic. LOL.
