India won't miss Tendulkar as much as they think they will, hasn't done a lot for a while and when a decent player like Badrinath is unable to get in the side then maybe things are a little bit better than they think. Having said that i'd still pick Tendulkar over Yuvraj and he probably has more in the bank than Ponting does as Ponting has been wretched for nearly 3 years bar a few months.
Personally I hope Ponting plays the ashes double header as i think he has gone and it would help us but he has been a wonderful player and both are starting to reach Viv Richards style naff ends to careers (1 ton in his last 20 tests) which in the short term are tarnishing their brilliant careers and with it some peoples memories might not remember them as great as they should. Dravid did it right, went out on a massive high really as his brilliant tour to England was fresh in everyones mind when he went.
I just hope we aren't repeating this thread in 12-18 months time about Kallis.
