I envisage that eventually they will adopt the tried and tested system of mainstream Churches. Hold the main sermon on Sunday for everyone to come and socialize, and drop midweek meetings. Keep the hall open throughout the week, manned by retirees, looping videos, so the lonely and religious zealots have somewhere to go and meet or meditate.
I think this could happen within the next 5-10years. They will have regular assemblies at regional cult complexes at least a few times a year to drill for fear and raise a few dollar$.
I see them cutting to just one meeting a week in an effort to make the religion easier and more appealing and keep inline with more mainstream religious cults (I'm talking about you Mormons). It's hard work trying to make a pseudo Jewish/Christian cult stay viable in this age of information.
