Double whammy perhaps? Looks like Pidgeon will retire after this series too (edit - someone referred to this earlier so this is just another source):

I can honestly say I will greatly miss those two in the game. They are the greatest Australian bowlers many of us have seen, and for me Warne is the greatest bowler of all time. They have done terrible things to English batsmen over the years, and without them we may have actually had a chance in the nineties!

Will Australia and the cricketing world see the likes of McGrath and Warne's record-shattering feats again?
