I don't agree with the point Manik makes about India being better on paper as a batting unit.
SA batsmen are in prime form and even though Indians are doing good as such,Hashim Amla,AB De Villiers and Jacques Kallis are in much much better form than Dravid,Tendulkar or Gambhir.Sehwag is only indian batsmen who is scoring as consistently as the 3 South africans.
So,I don't think India will win the series.Would surely be special if they do.
