The US House is not involved in trade policy, 10 members of congress is less than 1 in 40, the US trade rep doesn't have to act on letters like this other than writing a reply to them, Microsoft's/the concerned Congressmen's "case" is really weak, few Japanese people have ever chosen an Xbox in their market, with no anti-competitive measures neccissary, the current clinate in Washington, DC is openly hostile to tech companies (except folks from Seattle and the bay area,) Xbox's status as a "US import" is really questionable since they are made in China, Sony's exclusivity agreements in Japan, specifically, are aimed at Nintendo, which has a dominant position in that market, the 98 percent figure won't pass muster either since a Japanese court or trade body would include Nintendo's market-share, Xbox stopped investing in Japan over a decade ago-the actual cause of their low marketshare, etc. There's a billion reasons why this letter means nothing.
