I found this gem, I am using this angle to my spouse out of 'concern' with some of our JW understandings. It started with John 10:16 and our view of the 'other flock'. The inconsistencies with it's reasoning and then this thread on the 144k. This post was written 6 years ago, I looked up the scripture Matt 19:28 on the JW website and found this article written sometime within a year of this post I believe? I would say they read here and were covering their butt? It's this article :
W10 3/15 pg 24-28.
Sorry I can't get it to copy and paste on here.
