The racket that you guys are talking about is selling in HK as well. The O3 white with the 12 pt and 6 pt painted in pink. But it is called O3 White XF. It is slightly different from the O3, but it looks identical to the racket that Maria is using (with the 12 pt and 6pt painted pink, and Maria's autograph).
BUT. The racket that Sharapova is O3 white, not the O3 WhiteXF. (although the 12pt and 6pt is painted in pink). When she came to HK and play in the Hong Kong Watsons Water Challenge 2007 this year, I have had a 'feel' of her racket and took some photo of it (because I know the stringer quite well, so he offered me a chance to look at her racket when he was stringing the others.) Anyway, it doesnt matter how I get in touch with her racket, what matter is I can surely tell you guys that her racket is being customised, and is nowhere near the retail version(O3 white)... Although they both have the O3 holes... The writing of her racket is totally in differenct place of the racket... the butt cap is different, her racket doesnt show the statistics of the racket (e.g swing weight, length, etc), and also there is an autograph on her racket.
Hope this imformation could help.
