I honestly think that all the changes over the past 5-6 years are part of a plan that ultimately ends up in the 144,000 being made figurative. The Society realized they had a problem: The partaker numbers weren't going down anymore. They had maintained a very steady level for a long time. So I think they came up with a multi-part plan to arrive at that final destination, but a little at a time so as to try and avoid a schizm.
First step was the change in 2006 (2007?) to declare that the sealing wasn't completed in 1935. This was intended to lessen the pressure caused by the 1935 teaching. Because if new partakers were only replacing old ones who died unfaithful, it would mean Jehovah is the worst character judge of all time. This change, of course, caused the partaker number to rise, but I think they were anticipating that to some degree.
Second step was the de-mystifying and delegitimization of the anointed out in the various congregations. This is necessary, because if the 144,000 becomes figurative, it would open a massive floodgate of people who are convinced they are going to heaven. You'd quite possibly end up in a "more cheifs than Indians" situation. Better to start preemptively undercutting any illusion of authority and cut the partakers' importance down a few notches in the minds of the R&F. So, a statement was made in a study article 2-3 years back that the anointed not in Bethel don't have any special insight or communication with God, and are basically nothing special at all. More recently, I think the statements indicating a good number of partakers are likely mentally unbalanced was meant to calm people's confusion about the quickly rising partaker numbers.
Third, and latest, step was cutting the general anointed out of the F&DS altogether. Now, all the pieces are set. The anointed no longer have any position of importance or authority (not that they ever had much, but mentally they were still held in high regard). All "theocratic" authority has been consolidated directly to the GB. So, when they finally make the 144k figurative and the tide of new "anointed" starts coming through, there's no potential authority challenge.
