Kotaku: "Street Fighter IV won't be officially released in US arcades. But that doesn't mean it won't be released anywhere outside Japan. Take Australia, for example. Or Korea, or Singapore. It might come out there!
Capcom's Yoshinori Ono has revealed that while the game won't be shipped to the US thanks to a market "on the decline", there are other markets in the Asia-Pacific area region that Capcom are looking at."
