Microsoft getting half a dozen exclusive RPGS, moneyhatting SquareEnix for some exclusives and FFXIII multiplatform, helping create Mistwalker, reaching out to Japanese Indie developers.....all for what? 1 million in sales?
Pretty sure, Microsoft doesn't care about the market which doesn't give a shit about them either. Which is not to say that Microsoft is purposely sticking it to Japan, it's just they're not going to out of their way when the main battle is mostly going to be fought in Europe. That's the focus, and you can already see signs of that in putting Forza at launch, exclusive Fifa content, and really ramping up production in their European studios.
