Nothing official was released. A newspaper said 360Ks, Arum said 400Ks in an interview... In the end I guess its close to that but it doesnt really matter.

You got more than just the word of his promoter? Is there no official site to check on these numbers?
I would like to see something official too. I don't exactly trust the word of Mr. "Yesterday I was lying, today I am telling the truth".
