i think it is to early to tell. wait until after roland garros and then i can predict. someone in the top 10 might have a bad tournamnet at the french or someone like daniilidou, myskina, rubin, schnyder or bovina might have a great tournament and move up to say #11 or #12 and then they will be close to the top 8 and if they pull off some great wins or someone in the top 8 has some bad performances then the top 8 for one of these players might be in reach.
