In the Brazilian website site about volleyball, the pools of the 2008 Olympic Games are:
Pool A: China, Cuba, USA, Japan, Poland and Venezuela
Pool B: Russia, Brazil, Italy, Serbia, Algeria and Kazakhsthan
They are sure becuase they said that pools are definitly.
I don't write this phrase in English:
O sorteio já houve? Pq no melhordovolei.com.br diz que já ocorreu e foram definidos os grupos.
