Three series have gone by now, with the same side batting first.
First there was the Pepsi Cup, where India batted first in all four matches against the West Indies (the last three were when they were put in by Lara).
Next came the Hero Honda Trophy, where Sri Lanka defended totals four times in a row (including the rained out game) against India.
And now, in the Chappel-Hadlee Trophy it turns out again that Australia has batted first on all three occasions!
