Monsieur, as a rule of thumb everything the Watchtower has ever said is meaningless, irrelevant or misleading. You suggest there are bigger things to come from them ...bigger lies and bigger irrelevancies.
The 1914 doctrine as others have pointed, out has been the magic key to the success of the org. Not that they were right, they got the prediction quite wrong (1914 was originally to have been the latest date for entire restoration of the earthly paradise) but being in control of the information through their publications they always have--- and very much still do--- massage the ‘truth’ of what they say to gloss over their errors.
I see the direction the WTBTS are aiming for is to be like the biggest Christ cult of all time; the Roman Catholic Church, which although now declining, has through its wealth and political connections been able to ride out every criticism on the basis of self appointed authority and propaganda. The WTBTS is nowhere near this ideal so they will continue to struggle for religious credibility.
The JW authority was on the basis of getting 1914 right. This doctrine is becoming so old hat and chewed about that they will eventually try to claim divine backing without their sacred year...not an easy task! After all wrong calculations and wrong outcome over the year 1914 hardly make for evidence of divine attention.
