Myself as well others have assumed that the WTS is being deceptive in its proclamations that its under a heavy burden of debt . The sale of the organization's properties in Brooklyn New York grossed close to a billion dollars US.
The sell off of many of the WTS's branches around the world could be added to that accumulation of wealth.
The organization now is in development of a new UK branch to cover the UK and surrounding countries.
In others word the WTS has never been richer in its entire history. The numbers cant be covered over, although the WTS has made an attempt to do so.
The new master plan as described in the letter to all congregations in the US , appears that the WTS wants congregations that have low attendance in numbers that they should perhaps sell that Hall and merge with another Hall, selling off the mostly old and inefficient Kingdom Halls. Once again there's a fattening up the WTS coffers or a fill up the renovation fund to update and modernize already functioning Kingdom Halls.
This new approach of modernization is being done so to appeal to the publics eye as an alluring aspect.
So yes in the immediate future you will see Kingdom Halls that look expensive and electronically modernized , there is an hidden agenda by the WTS to do that, its called self promoting commercialization
