I don't think the new NWT will have much in the way of re-wording... Just the same old - same old - NWT minus square brackets repackaged with a little bling eye candy!
Sometime ago ( http://www.jehovahs-witness.net/jw/friends/224140/1/So-wonderful-little-and-other-punctuation )
I mentioned these new blinged out NWT versions that the GB and some preferred travelling overseers were sporting last year at the District Convention. (There be pictures on Facebook!)
The Bibles versions they carried were a bit fatter because they included the appendices of the reference bible but in the deluxe leatherette size.
Maybe the marketing guys at Bethel decided that grey and silver may appeal more (than the black or maroon gold edged) to the ever more elderly and passing away generation that was promised to already be in a paradise earth.
