Honesty the patrons have been through some rough patches with P and P over the past soon 3 years so they are hardened and P and P will survive this one as well.
The usual cycle that we know all too well is: develop, promise a date, delay, promise another date, delay again, finally they deliver, people love it, some complain it's too short for x months (you know the usual..), they start a new cycle.
They are roughly maintaining the core patron base who knows how this cycle work for 2 years or so. Yeah some patron come and goes, but the core roughly stays.
But your are right they are not growing their base and they will not grow it with the current approach, but they will also not close.
