- World Number One Crushed Out
2007 World Champion Lin Dan defeated third-seeded Peter Gade in straight sets, 22-20 and 21-16, in 49 minutes to meet Indonesian Sony Dwi Kuncoro in the semi-final. This semi-final date repeats the 2007 final in which Lin Dan emerged as the best.
Sony Dwi Kuncoro won a not-really-surprising quarter-final match against top seed Lee Chong Wei 21-16, 14-21, and 21-12. Sony also defeated Lee in 2007 World Championship third round. After this result, Lee never won even one prestigious title, All England and World Championship, since he became the world number one in August 2008.
