I definitely sensed this is preparation for more to come
they have "simplified" the truth to drop much of what has bitten them in the ass
the new methodology is very mainstream compared to the century past but I am certain this is laying the ground work for all date setting etc to be "not the point".
The WTS can shift the conversation from dates like 607 and 1914 to encouragement and application instead of mathematical formulas
after a few years of this new "focus" they can quietly leave out the "old" focus and eventually lose the original teachings all together
