The rumors started because apparently all the bibles are on backorder. This rumor is not only going around with us on this board, but among JWs as well. So it's not unlikely that his elder heard it too. No matter how nice of a guy he is, he probably isn't immune to the rumor mill, especially if it comes from a source he trusts. Doesn't mean it's going to happen.
And let's face it, language evolves. Take the King James bible. The language of the day is no longer valid. We have new terms for the same ideas. So, a legitimate bible (not that I'm saying the NWT is one), might periodically update the language to the times. For instance, let's say 100 years ago, somebody was spoken of as being gay. That word carries a whole new meaning today.
We are talking about translating ancient languages into a best-fit wording in English. And the best-fit does change over time.
Yeah, no new release at the DC, unless they're going to do it at a future DC and then release to the other congregations through a special talk. There was a God's Word theme to the DC. Maybe they couldn't get enough printed in time. Keep in mind that it's a significant outlay for a large book like that. Money they won't get back until they start selling getting donations for them. So maybe they want to release differently so that they don't have as much of an up-front cost.
