Yonex just launched Yonex Nanoray 900, which was used by Saina Nehwal in the Thomas/Uber cup.
The flex is stiff and comes in 2U and 3U.
The recommended maximum tension is 25lbs for 2U and 24lbs for 3U.
The color is called iron gray, looks quite similar to Taufik Hidayat's limited edition Arcsaber 11.
May think of acquiring this racquet, we'll see.
