I think there is some legitamacy to this theory, I am the literature servant in our hall and we have been back ordered on Reference Bibles and the Black and Red Deluxe Bibles for about 8 months now. All we have are some of the crappy paper bibles and a few hardcovers. Maybe because they aren't printing them and are instead waiting for the release of this NNWT.
Interesting, I've been trying to get a new Bible from the back for a while. I have a reference bible on order and the servant has apologized to me a couple times even though I wasn't pressing him. I just need a new Bible. We don't even have any of the paper back Bibles at our congregation. He told me those were on backorder too.
