I don't think so. If they're smart and cut off the greater losses, yes... but there will be a loss of "prestige" in doing so. They could live a long time on what they've captured, but only by admission of what they've lost.
My guess: TEC runs out about the time the current "ownership" expects to pass on.
You're correct...a good example of the oncomong implosion is the Diocese of Newark. They are expected to close some 40+ parishes within a a year. But what they are doing is consolidating them into some of the larger churches, the older ones that seat near 1000, that were built 70-80 years ago, at the apex of TEC. These buildings are cost afortune to run, heat, and are literally falling down, and will require enormous sums to make them suitable for use, let alone safe...and the diocese will have to front the cost...
