Well, if there are any changes, it will be followed with an announcement that we can't accept it untll the new Service year, in September 2013.
So if it is a change in how you talk to your DF'd relatives, blood doctrine, neutrality, birthday celebrations, pant suits for sisters, beards for men, you may be punished until September 2013.
All of these will be replaced with an additional night for family worship, too.
