I emailed Gary Anderson and he put together a summary of what he expects.
<<<excerpts from his email first>
Now his summary ... this is converted from his format:The ISSF Rule changes that were incorporated into the new 3-P Air Rifle Rules were all officially approved by the ISSF Administrative Council when it met in Moscow on 30 June. We left Moscow with some still unresolved issues that we are getting worked out now that the Olympics are over. In addition, the President and Secretary General didn’t want any rules announcements until after the Games. The ISSF Committees meet in November so the plan now is to release, post and publish the 2017 Rules immediately after that.
In the meantime, I do not expect changes in any of the new rules that were approved in Moscow except for one possibility in the Shotgun Rules and a couple concerning electronic target complaint resolution. To help you and the NCAA Rifle leaders in your planning, I prepared a Summary of ISSF 2017 Rules Changes that will impact on Rifle shooting. I cannot give you an absolute guarantee that there will be no further changes, but I think you are safe in assuming that these ISSF changes are on the way and that athletes should prepare for them.
