As much as I would like to witness another duel between Lin Dan and Lee Chong Wei, as visor rightly pointed out that the wild card is a courtesy, and Lin Dan really has no "right" to it. He's already been given one wild card and he could have easily started his come back attempt earlier by one or two tournaments. Assuming he would have won those, he could have reached world top 24 without a problem. At that point, China could have chosen CL, DPY and LD to play. I'm not actually sure how the rules work, but LD was technically world #83 at cut off for WC. In the most recent update of the world ranking, LD is not at #58, flying through the ranks by 25 places. He's obviously now top 64, and if China chooses to do so, they can send only Chen Long and Lin dan, and therefore satisfy BWF's limit of players per country. However, I'm not sure if they use his #83 rank due to cut off, which would not grant him the option of playing World Champion ships even if everyone between CL and LD did not participate (which would be Du Peng Yu, Wang Zheng Ming, Tian Hou Wei, Chen Yue Kun, Xue Song, Gao Huan). Plus, that's a huge sacrifice of having 2 world top 10 players drop out of World Championships for the sake of getting Super Dan in. In my books, having Lin Dan and Chen Long in the world championships would present China with the best chance of capturing the Men's Singles title if they're lucky enough to be on opposite sides of the draw.
