If people in the congregations are speaking authoritatively and saying that the new Bible release is a fact, I see two possibilities:
1. The rumor is false (or at least uncertain) and information from apostates (hey, that's us!) is actually leaking back into the congregations and being taken as fact
2. The rumor is true, and the new Bibles are already sitting at the Kingdom Halls for immediate release after the Annual Meeting program. They did that sort of thing before when Organized to Accomplish Our Ministry was released in an announcement after the spring Special Talk one year. The books were shipped into the congregations in advance and the elders were instructed to tell no one except the literature servants prior to the actual announcement.
