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
may not 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.
Actually, there is quite a bit more demand [for SFIV] in Asia and Oceania than there is in North America. To be honest, the video arcade culture in North America is on the decline. There are not that many venues left for arcade video games any more.
We have seen that there is a lot of value in the markets of Korea, Taiwan, Hong Kong, Singapore, New Zealand, Australia, as well as some other markets.
So USA, no, Singapore, yes? Kooky.
