Since any substantial release is always done by Saturday, I can presume that Fatherless's comments are correct.
I would concur that the NWT needs a major revision, but I doubt we will see one any time soon.
Reason 1, the cost. Every Jw would want/need a copy of the new edition, and the Bible is one of the more expensive to produce. The WT society is too short of cash to produce a translation (and then to re-translate to other languages) in 7 million copies
Reason 2, the Society doesn't have anyone qualified to revise the translation. Wait a minute , they never have had any one qualified to produce a credible translation in the first place... never mind
