I guess ZJW is being nudged very strongly to retire by LYB since there are a lot of news articles where he's plainly stating that she's always sick, incapable, not needed, unwanted, too old, etc. He mentions he would do his best to keep her on the team but always states that if she wants to leave he won't stop her. I read one article where he talked about how YW/ZJW were still high in the world rankings and that he would keep that in mind, but I don't really get why it was mentioned if he has no intention to put them back together. I think he just likes having them at the top rankings because when they don't play, his lower-ranked player all get to qualify for things that they normally wouldn't - like WC etc. LYB only does this for his WD since they're still dominant and can be interchanged and still produce a top pairing. Look at Xie Zhongbo/Zhang Yawen combination for instance. They haven't won a title this year and only took two last year I believe, and have been consistently losing to foreign players (a reason that LYB split up ZJW YW was cause they kept losing to foreign pairs) in the quarters and semis yet they are still paired up.
