They might get rid of reporting hours on paper, but they won't get rid of preaching, and I'm with the other posters here who assume they'll introduce electronic reporting instead. Preaching defines 'spirituality (effort) for Jehovah's Witnesses, you can't eliminate it without pulling the rug out from under pioneers, Elders, etc. who enjoy status for making that extra effort. Preaching also gets you places in the organization, I think you need to pioneer for two years straight to attend the School for Kingdom Evangelizers, for instance.
Reporting preaching hours on paper might go. Preaching won't.
