Ryu doesn't speak English. I have no desire to ever hear him speak it. In fact, as far as I'm concerned, he only knows three words: hadouken, shoryuken, and tatsumakisenpuuuuuukyaku. The rest of the time he spends silently dragon punching waterfalls and walking the Earth with a sack over his shoulder.
Here's a trailer that shows off some of the story stuff from Street Fighter IV, including a bunch of English talking.
I really hate to be this sort of voice acting snob-guy, but... dude, I'm so setting this to Japanese as soon as I get it.
