Even if Rutherford would be disfellowshipped were he to be resurrected today, he's still foundational. The JW "church" is built upon the Rutherfordian rock.
My thought is that they will eventually try to make the 144,000* "go away" and that only the GB and those closest to them will be considered to be annointed and the FDS. And the Memorial will be further bastardised to the point that it will be a live broadcast to the world's Kingdom Halls of the GB partaking, to the exclusion of all others.
Not a prediction, just a thought. They've uncoupled the 144,000 and the FDS. The above scenario might make a logical follow through.
