I will see how long the ICC can try to curb the flow of T20 in international cricket. We will see! Sometime or the other, its going to give way. People didnt know about the potential of this format to entertain people, and thats why ODI's did well. Tests will always have its place (although only the die hard fans of test cricket will visit it as opposed to earlier when people had one lesser option with the non-existence of Twenty20 cricket)
