The local congregation (midwest US) is out of English bibles also. My thoughts:
The Watchtower Bible and Tract Society has one of its primary (supposedly) mission to distribute Bibles. In this it is failing. There can only be a few reasons. Here are three reasons that I can think of, in order of probablility.
1. They have produced another edition and are planning to release it soon, possibly at the summer conventions. Or, they could announce the release at the conventions to be available later in '13.
2. They are hopelessly broke and cannot afford to print them.
3. They are incompetent in management and have lost the ability to meet the needs as they come up.
Does the NWT need revised? YES!
Does the WT Society have qualified translators who can do the revision NO!
Have they ever had qualified translators? NO!
Does the WT Society care if the NWT is in agreement with the original manuscripts? NO!
Does the WT Society care if the NWT supports their pre-conceived doctrines? YES!
What will come out of this?
If the NWT is revised it will be 99.9% the same old NWT with a few revisions to support WT doctrine. For example, in the 1950's NWT New Testament the words in Revelation were 'older persons', but the later editions the words were changed to 'elders'. This mirrored the NW terminology change that came in the early '70's. Neither word choice is really any better than the other, but the change supports their doctrine. That is all they care about. We will see similar word choice changes in any future revision.
Anyway, that is my two cents worth
