Per a recent BOE letter:
-- New manual will be softcover
-- Elders can keep their old elder manual if they choose
-- Elders warned never to leave the new manual where others can see it - it is for elders only (bolded in letter also)
-- A new term will be introduced - "Brazen conduct" will be alongside, or even replace, the term "loose conduct" as it "more accurately reflects the original Greek word translated 'loose conduct' in the New World translation"
That's pretty much all of the semi-interesting stuff. The bulk of the letter dealt with which chapters to read prior to the next elders school, what to do (re: the textbook) if an elder moves in or out or is newly appointed, etc.
The most surprising things to me were (1) Softcover? Really? You're so cash-strapped you can't even afford to hard-bind a few thousand books for your "elite"? and (2) "Brazen conduct" is a "better translation" than the NWT's "loose conduct" - seems to be a bit of a dig at dearly departed Freddy.
