ESPN today will be making a massive announcement regarding the addition of a new commentator to its World Cup broadcasting team. The press conference is scheduled for 2:30pm ET. But the question is, who is it going to be? All ESPN says is that it’s going to be a “marquee FIFA World Cup personality.”

But who is out there that could be picked? Martin Tyler has already announced as the lead commentator. Andy Gray has been picked up by Fox Soccer Channel for its World Cup analysis. Could ESPN be announcing a US commentator to appease the critics? Or is it a marquee name from international broadcasting? Or could it be an American name that everyone is familiar with but he’s from outside soccer?

UPDATE: ESPN press release just out announces the addition of former German National Team Coach Jurgen Klinsmann to the World Cup 2010 broadcast staff as an analyst.
