I know that if you care at all about SF4, you've already seen the new introduction trailer for the new additions to Super SF4. Well and good.
However, you may not have seen the Japanese version yet, which in my opinion contains vastly superior voice acting, especially in Dudley's and Makoto's case. The new Ultras are sick, especially Dudley's Rolling Thunder, which thanks to 3D camera angles is now revealed as an homage to the Dempsey Roll from Hajime no Ippo!
To view the trailer, just click here and select the SUPER Promotion Trailer #4. Oh, and bonus tease at the end...heh.
