When India won the first T20 World Cup way back in 2007, it was an upset of sorts. But those days, all the teams were learning the ropes and the surprise factor around the Indian win was more because the Men in Blue had a disastrous 50-over World Cup earlier in the year.
Since then, in the six more World Cups before this, there has been the odd upset here and there. But never has there been a World Cup like this, where upsets have virtually become par for the course.
