the difference between the russians and the belgians and the willim sisters is that the russians have come as a contingency rather than a pair. the top 3 russians are very competitve with the other top players and the others like sharapova, zvonareva and petrova and bovina are in a position where they could start to really compete with the top players. and dont forget the younger ones like dinara (who has taken 2 top 10ers to 3 sets in her last few tournaments), anna c, kirilenko, douchevina, linetskaya. but the russians arent the only ones with the chance to be up there, players like sprem, na li maybe even ivanovic and vaidisova and karatantcheva and tati.
of course the williams sisters or the belgians, davenport, capriati, mauresmo also have the chance to get up there, atm i dont see anyone or any 2 players dominating but i see a whole lot of them being up there winning titles next year.
Go the aussies! stosur!!!
