Doug Mason:
1. Does the NT still accept the 27 NT books provided to it by the 4th century Trinitarian Church, including Athanasius and the Roman Emperors?
Yes.
2. Does the OT retain an allegiance to the Hebrew text or to the Septuagint (for example with Jeremiah, especially in regards to the "70 years")?
Yes.
3. Will it say the changes are due to a better understanding, to Lower Criticism, additional information since the last release of the NWT, to recognition that the MSS evidence shows that the text is unreliable and has to be reconstructed by Lower Critics?
No. (With the exception of the alternative conclusions to Mark and John.)
4. Which text(s) does the revised NWT rely on (eg., Westcott-Hort; Textus Receptus; MT; variety of LXX), or had it constructed its own source from a selection from many sources (eclectic)?
Almost certainly the same as before.
5. How will the WTS manage the transition from the previous version to this one?
Publications from January 2014 onwards (including magazines actually printed earlier but dated 2014) will quote from the new translation.
6. Will any JW prefer to refer to the earlier version?
Probably.
If so, what will the WTS's attitude be to those who do not change over?
Public executions for anyone keeping the old version - well... probably not. They might 'suggest' that JWs read from the new one when responding at 'meetings'.
7. Will the over familiarity with the earlier text unnerve any?
Maybe.
