Not predictions for 2013 per se, but a couple I could see happening in the not-too-distant future:
The Society takes the hundred year anniversary of 1914 head-on with more spin and disinformation. Already laid the groundwork with the "100 Years Ago" feature in the new yearbook. "If we write it, they'll believe it." It has worked for decades.
The annual Yearbook of Jehovah's Witnesses will be discontinued in book form. Now it will be a downloadable 30 minute video presentation highlighting the worldwide brotherhood and preaching activity. Everyone will watch it together and discuss at the Service Meeting. The worldwide statistics will either be missing, or scroll by really quickly like ending credits
