When do you think Tim and Manu are going to retire?

At the start of this season, from things I read, I had a feeling this was going to be Manu's last year and that Tim would probably play at least another year after this one. I'm still thinking Tim will play at least next season, but for some reason Manu's resurgence this year (before injury) made me start to think Manu might have even another year left in him, but then again maybe the reason he was playing so well this year (and making less stupid turnovers) was because he knows this will be his last year.

Of course, what happens in the playoffs will probably be a big determining factor.

Anyways, I'm watching this season like it's possibly Manu's last and Duncan's second-to-last.
