Judging by recent child abuse cases, UN scandal and Blood doctrine change that the WTS is being exposed and that the rest of the world is taking note.
Well, you metnioned three things that were given considerable discussion here at JW.com
First of all, the child abuse cases. I've never really thought of child abuse cases as severely hurting the membership of any religion. Catholicism and Mormonism are churches that have lost millions of dollars in child molestation cases, and they continue to grow, expand, and use their PR effectively to highlight their good deeds.
Now, The UN scandal. Cmon, almost nobody outside this web site and the upper schelons of UN and WBTS has even a cursory knowledge of the involvement with the UN, and, to tell you the truth, I don't think most people care. I don't even care (I know I'm the minority here on this one) and this is why: JW's don't really have a high-profile reputation as UN protestors, they're those people who annoy the heck out of their neighbors on weekends by trying to teach their interpretation of the Bible. I doubt even many JW's believe the UN has any reference to the Bible anyway. The story hasn't even made it to my newspaper. Besides it's such a kooky doctrine anyway...
Now, a revoke on disallowing blood transfusions is something that I feel could lead to considerable attention although I don't forsee the WBTS as making a firm stand on the Blood Transfusion issue. Doing so would seriously hurt their image, and everyone here and their neighbor down the street knows it (assuming that the neighbor knows anything about Dub-dom). I think it's more reasonable to expect this issue to be relegated to the same extent as voting (something that's looked down upon but would be classified as a serious sin). Both stances (the blood one and the voting one) have led to many people dying, and yet, how many people left the org when new light came out about voting? As Kurt Vonnegut writes in Breakfast of Champions, "Doodley Squat!"
Sorry if I come across as rude, please forgive me if I come across as such, but many people have had successful careers launching high demand organizations with members that are coerced to believe whatever the hell they want them to (again, look at Mormonism and Catholicism) and I don't forsee their organizations going down the toilet. The governing body is a group of extremely intelligent men, similar to a political body or a law firm, who have many people behind them, and are willing to support them out of fear. No matter what kind of humilty they excude they represent the truth of Henry Kissinger's words: power is the ultimate aphrodisiac.
So, to make a long story short, don't hold your breath, at least, until they allow JW's to
