Some of the issues are not new. Rapture was taught to us in the late 1980's, and this was the first time I have ever encountered this word. Rapture became increasingly popular with extreme evangelical movements and WT just jumped into the bandwagon with them. Other issue is a pushed by necessity. As 1914 became distant year in a human history, they need to unwrap all the BS that was based on this doctrine. One of them is the 1918/1919 idiocy when they claimed that Bible Students were chosen by Jesus after for 3.5 years he was examining world's religion and discover a pack of prisoners charged with sedition in USA. I think it was 1919 year when they started to claim to be God's exclusive channel of communication. In order to unwrap from 1914, they need to erase all the theology tied to it. Since it been almost 100 years, they have must create new sets of doctrines, but this takes a years to establish. I see it as releasing balloons in the year, and which does not get shut down will eventually groomed as a new "truth".
