The Battle of the Japanese Consoles have been raging for a year and no one has seen this kind of conflict since Godzilla took on Mothra. Twelve months later, the scores, though not final, are out. So far DS and DS Lite has sold a total of 6,385,193 units in Japan (as of March 12). Sony's PSP sold only 3,135,588. The Japanese round clearly goes to Nintendo, but Sony isn't ready to thrown in the towel just yet. The U.S. round is a much closer fight. Of the 5.81 million units Sony shipped to the U.S. by the end of 2005, "more than 4 million" had been sold by mid February 2006. Meanwhile, Nintendo reported 3.97 million units of DS sold in the US by the end of 2005. So basically it's a tie. The fight's not over. And accountants are standing by to crunch the numbers as soon as they come in.
there's no doubt the UMD has been a huge failure as far as movies go, but PSP units are still selling.
