They're getting older now and know the competition is getting harder and they have been overtaken at certain tournaments, so don't kid yourself. I would find it difficult to believe they will have many more long streaks esp Venus, she'll be gone from the game within a year I think. Serena may hang on for a bit but not past the age of 25. I hope they recover well though from these injuries but I feel that my predictions may well come true. Best of luck to them in the mean, can they prove me wrong??!!
