It really depends on events. The WT has never been pro-active and forward-looking as it likes to project itself. In reality they are simply reactive, and pretty slow at it, so that by the time they do something, the target has already moved.
What they would dearly love to get rid of is the Blood doctrine, but the fear of heavy damages from those whose family members have died has caused them to simply try slowly reversing out of it over decades, meanwhile innocent ones, children even, still die.
They would like to bury 1914 so it slips in to oblivion like 1799 1874 1925 1975 etc
They have a problem of huge proportions with that though, their whole edifice is built upon it, all their claims are linked to it. Talk about built on sand !
They would need to get rid of the shunning if they wanted to go more mainstream, which one day they may wish to do, if being so weirdly different is a huge barrier to recruitment they may have to, and so they should, it really is the most unloving, unchristian, unscriptural of practices, the very worst kind of bullying. This doctrine/practice too has caused many deaths, one only a few weeks ago.
It is my gut feeling that they will tweak the 1914 doctrine a bit to make it less ludicrous, but they have an uphill battle on their hands, and even a tweak at this stage may wake up a good number to the reality.
The reality being that the WT is an erstwhile Publishing company which now makes its bucks from property dealing, posing as a religion.
