my prediction for the individual events

Vault
1. cheng fei- 6.5/6.5 she has the best form in the world right now.
2. the korean girl (sorry i forgot her name) 6.5/6.5 she may even do a more harder vault beacause she is fearless
3. Jade BArbosa 6.5/6.5 with that new cheng vault she is doing, she has really a great chance in medaling.
4. alicia sacramonie 6.5/6.3 unless she will do an amanar vault, she can also medal.

UB
1. He kexin 7.5 she has the best execution in the world nd the most dynamic worker and besides she is a chinese.
2. Liukin 7.7 she may have the most difficult A score and very elegant, with that dismount (just totally ugly) i feel that she will not going to get the gold.
3. Semenova 7.6 she is just beautiful to watch with those beautiful combo she does she may even beat liukin.
4. yilin 7.0+ unless the top 3 will make an error during the event finals, she may snaatch a medal.

BB
1. Li shanshan7.4+ she is just a master in this apparatus. no one chanreally come close to her and even if she will make an error, she will syill get a medal.
2. jonhson 6.8 she has the biggest tricks but come on, she doesnt have the "beauty factor"
3. liukin 6.6 she is just beautiful in this apparatus but she need to upgrade this routine to have an edge with the ohthers.
4. Deng linlin 6.8 she has a potential score of 7.3
4. Nistor she is just solid in this apparatus some may say that she doesnt have the elegance and beauty but come on, she just sooo consistent in this.

FX
1.cheng fei 6.5 remember cheng fei will be doing a dos santos move which will definitely upgrade her A score. and she is judt a master FX
2.johnson 6.4 she needs to be more steady with her skills becuase in the dance department she is just lacking.
3. Jiang yuyuan 6.3 she has new FX routine but honestly I miss her old routine. she needs to feel more her new routine beacause it seems that she is not yet comfortable with it.
4. SAcramonie she has the skills but there is lacking with her.(I just don't know) she really need to change that routine bec. she's already using it for almost 3 years now.

For the AA
1. Johson she needs to upgrade her UB and with that amanar vault, she will be a huge favorite.
2. Liukin. its true taht she upgraded her UB but she still nedds to work on with her vault. remember that many AA contenders will be doing an amanar. and also her FX needs to be polished.
3. Jiang yuyuan she is said to be doing an amanar and a good score from UB and FX she just need to work with her BB.
4. Nistor many people may say that she lacks artistry, this girl is just so consistent. others may have the elegance but lacks consistency(like liukin).
5. ferrari she is said to be doing an amanar vault and good in FX,UB and bb. but remerber she is having some injuries right now. this girl's determmination to win is just admirable.
6.Jade barbosa she just adorable.. hehe
7. the korean girl- she just need to improve her FX and BB and she will be a contender. I feel that she will be the darkhorse coming brijing bec the koreans are known to throw difficult skills

you can react with this and besides there are still few months for other gymnasts to improve themselves.
