You may have a point but let us look back at EPL soccer on which IPL is loosely based...I dont think it has created any regional upheavals there. If the people are foolish to believe and practise regionalism, why blame cricket for it!! It starts with regional political parties and more so lets not make cricket a scapegoat here.
yes, it is surely commercialization to the hilt but then it has not started yet...it started decades back and it is only being polished further.
