I am thinking that the "Ten Year Plan" that some have spoken of is the most likely scenario. The Org. has to both attract new members and retain as many existing ones as possible.
So I think they will let the recent changes "Bed In" for a while, maybe a year ? before introducing the next "Biggie".
I think that may well be a relaxation on celebrating Birthdays and Christmas, which can be introduced as a "Conscience Matter", thus new converts can carry on, and J.W's that want to can celebrate those events too, those that don't can refrain, and feel superior.
I have spoken to a good number of ordinary normal people, in J.W Speak "Worldly" people, who mentioned not being able to celebrate as they have for all their lives being the main reason for their rejecting the J.W org.
Thoughts ?
