Retirements in Ashes series

Damien Martyn retired after the 2nd test in the current Ashes series.

Shane Warne retired after the 3rd test - once the Ashes were regained.

My next guess is :

Glen Mcgrath will retire after the 4th test.

Justin Langer and Matthew Hayden will retire after the 5th test.

The Aussies believe in spacing their retirement plans, right :)
