NPB Commissioner Ryozo Kato will be heading to the US to speak to both MLB Commissioner Bud Selig (1/5/2010) and COO Robert DuPuy (1/6/2010).
The three will likely discuss issues like the 2013 World Baseball Classic and an actual World Series where championship teams from each league in various countries battle it out for top honors.
=== UPDATE 12/29/2009 11:03pm JST
Seems Kato is calling his idea for a "real" World Series, the Club World Championship. If talks don't proceed very far with the MLB, the NPB could still move forward with expanding the Asia Series to include more countries in the future, like Australia, the Philippines, and SE Asia.
The idea, of course, would be to make the Asia Series so big that the MLB has to pay some attention.
