MEN'S SINGLES:
Lin Dan vs
Bao Chunlai
It has to be Bao's turn. If Lin doesn't stop winning, he must be from another planet! On the other side, Bao is only the second to Lin Dan. During this long Lin's dominating era, Bao and Chen Yu were the only two guys winning the tournaments! No body else.
Chen Hong vs Chen Jin
Never underestimate the champion! Chen Hong was the current Champion China open 2005 so far. So never too much to predict the champion winning one more round.
In Men's single, now, Lin Dan is too much for others to catch. For him, the question is not when to win next time, his problem is when to lose next time!
Top tier (always win

) : Lin Dan
2nd tier (capable to win at Lin's absence

): Bao, Chen H, Chen J, Taufik, Lee CW, Gade, and Chen Yu
3rd tier ( capable to beat 2nd tier but no chance to win): Lee HI, Roslin, Hafiz, KJ, Boonsak.
WOMEN'S SINGLES:
Zhang Ning vs Wang Chen
Yao Jie vs Kaori Mori
Zhang Ning and Xie XF and far better than others. Potential competitors include all other CHN players, plus other Chinese players out-seas.
MEN'S DOUBLES:
CAI Yun/FU Hai Feng vs HADIYANTO Luluk/YULIANTO Alven
KIDO Markis/SETIAWAN Hendra vs ERIKSEN Jens/LUNDGAARD HANSEN Martin
Top tier MD: Tony/Chandra
2nd tier: Fu/Cai
3nd tier: Eriksen/Lundgaard, Kido/Setiawan, KKK/CCM, Lee WH/Chong TF, Hadiyanto/Yulianto, and many other Chinese pairs under regrouping, and a couple Malaysia pairs
WOMEN'S DOUBLES:
YANG Wei/ZHANG Jie Wen vs CHIEN Yu Chin/CHENG Wen Hsing
ZHANG Dan/ZHAO Ting Ting vs
WEI Yi Li/ZHANG Ya Wen
Top Tier: all Chinese pairs
2nd tier: some up and coming Chinese taipei and Korean pairs
MIXED DOUBLES:
ZHANG Jun/GAO Ling vs XU Chen/ZHAO Ting Ting
HE Han Bin/YU Yang vs
XIE Zhong Bo/ZHANG Ya Wen
There is really none dominating in mixed double, even though there are four chinese pair in semi, but none in the WC. Who will win the mixed double, seems totally random. Look at Zheng Bo/Zhao TT, claimed 6 star HK open by beating many top pairs, still not good enough to play together. So no body knows who's turn next time.
