For our girls, it's not just the 2006-ers who will be dropping out
Laura Samson has just announced that the Junior Finals was her last juniors event
Renata Jamrichova announced the same thing a few months back
I think Iva Jovic has basically quit juniors (although might well play the Slams, so that's not quite the same - the East European girls have more financial pressure to move up early whereas Iva will have more flexibility)
But that's definitely quite a few of the real top players who are dropping out, as well as the 2006 girls
