Capcom-Unity moderator TAS chimed in to answer a question about multi-language support in SF4. Here's the skinny.
Will we have the option of selecting either English or Japanese voices in SF4?
TAS: Seth told me at Captivate that they were trying to work on the ability to allow players to switch individual character voices between Japanese and English, i.e. you could have Ryu in Japanese and Ken in English.
As for Ken's English voice actor, it's the same guy who voices Dante in Devil May Cry 3 and 4, and the Devil May Cry anime series, which is pretty good fit I think. Steven Blum has been my favorite voice actor for Ken so far, but the guy in SFIV should be a good alternative, especially since Dante's personality isn't all that different then Ken's.
