I think when the end of the line comes which is quite close then it will be time to close it.
BMI Regional will not warrant a seperate thread as its size and FF membership will be a hell of a lot smaller compared to BMI. ( unless they join Star and start doing M+C and 20K to get Gold )
I guess all good things comes to an end but for me BMI is dead and I am spending more time focused on my new programs now.
