All what i feel is, media is making a big issue out of nothing. Earlier when he spoke to Times about the recovery factor, these news channels made it as a big flash news that he might quit cricket soon.
I believe still, there is plenty of cricket still left with this legend so called Sachin Tendulkar.

It seems, his wife Anjali too have denied that he is going to retire.
'Tendulkar not quitting One-Dayers'
Tendulkar's wife Anjali told CNN-IBN that he has no plans of retiring.

What a good timepass for these media news channels

Personally i have a slight feeling somehow that he will play his 2011 WC as his last international series and then retire like what McGrath did in this 2007
