If Venus does not qualify by herself with enough points, then she will get the WC if healthy. Why, because she won a Grand Slam this year, Wimbledon. Also, she is a very talented player. Now I know that Nadia and Elena are too, but its that Grand Slam win that puts Venus one step ahead of them. Also, if you look at the Real Rankings, Venus is also ahead there as well. So, in conclusion, Venus should get in without help, and if not she deserved that WC position.
