Yes to Evert and Navratilova, no to Serena. I think Serena will dominate the WTA for years to come. It's come to the point where you don't ask what's the next slam she'll win, but what's the next slam she'll lose. She's too good and the top end competition too weak. Only way I see Fed ending up with more then her is if she suddenly and unexpectedly retires sooner rather then later (maybe she'll take pity on her competitors, but I doubt it as pity doesn't seem in her nature, just look at poor Sharapova). Federer will continue to win matches for a while but I see him slipping up earlier more and more often from this point on.
