Does anyone know when Polina Semionova's (ballerina) Biography will come out in English?

-Hey there! I'm a BIG fan of Polina Semionova and I know that she has a biography book but it's only in German for now.. here's a link:

http://www.amazon.de/gp/aw/d/3802537149/鈥?/a>

So I was wondering if anyone knows when it will come out in English (OR Russian, Im russian so I can understand if if it's in Russian :p)

Yeah so thanks if you know. And I believe that the title translated in English should be: Polina: From the Moscow suburbs on the great stages of the World

Thanks
