I think it is too early to come into the conclusion.But I feel that South Africa will be the best test side for at least a year or so mostly due to the fact that Australia are not the same Australia when they had McGrath, Warne and Gilchrist. I mean it is really hard to replace those players..Too bad for Australia that they retired around same time. Basically, Australia is trying to rebuild their team and they are going to loose games in the process .Talking about South Africa, their young players seem to be performing beyond expectations and I can't see any other team stopping them. However, in ODIs, I think Australia are arguably the strongest side. I am  really looking forward to the ODI series between SA and AUS.I am not sure why England is being talked about for the best ODI side after loosing 5-0 to India.
