Well,I don't really know
I'm guessing for Russia:Myskina,Kuznetsova,Demtieva,Zvonareva,... (I don't know how many players they can send)
USA: probably the Williamssisters,Davenport and Nvaratilova for doubles with Raymond
France:Amelie,Dechy (so I've heard) and Pierce I guess
Belgium:Justine will go for sure,Kim doesn't want to go,and maybe Els will go
I also thought Arantxta will play for Spain in doubles,Martinez will go too I think.
To be honest I'm really not sure besides Justine,Amelie and Dechy.But this list sound pretty logical.And o yeah,Daniilidou playing in her home country offcourse
