Who will be the next dominant player in the league?

Although it may be tough to accept, players like Iverson,Tim Duncan, Tracy Mcgrady, and Kevin Garnett are approaching their twilight years. Kobe will be 30 this year, but he is still going strong. We have a couple of bright young stars now who are already all stars, but it is imminent that they can only improve. I am talking about Lebron James, Dwight Howard, Kevin Durant etc. I think Lebron will be dominating the league in similar fashion to MJ, what do you guys think.
