The JW organization is probably losing more of their members than they care to admit. This will eventually force the GB to make more “adjustments” to stop the exodus and stabilize the membership.
Therefore, it's possible that after 2014 the Watchtower may gradually become more main stream. While I don't see them accepting the Trinity or Hellfire, they may open Heaven to all JWs, though confine them to a lower level in the Heavenly realm, while the GB rules as "kings and priests." Birthday parties may be permitted and blood transfusions will become a conscience matter. Tobacco use will become a lesser sin, meaning one could be removed as an elder or MS, with privileges restricted, but not DFd. The GB may even stay out of JW bedrooms and allow most sexual sins to be handled by one elder; much like Catholics confessing to their priests. But the Watchtower leadership will still take a hard-line toward what they perceive to be "apostasy.”
The GB may also take a few more pages from the Mormons. Perhaps requiring all young JWs, once they reach the age of 18, to spend two years in missionary work, either locally or in a foreign country. After the JW finishes his or her missionary requirement, door to door work will become voluntary for the former missionary. Most D-D preaching will be replaced by using TV, Radio, and the Internet to get their message out and to solicit donations. Like the LDS, the Watchtower will require tithing, 10% of each JW's gross income. The GB will be enlarged to 12 members. The Watchtower may even open a JW college. JWU will have many of the business, engineering, and legal classes that you would find at a secular college. But one course that will not be offered at JWU is critical thinking.
