A trailer for the arcade version of Super Street Fighter IV has revealed two additional characters: Evil Ryu, the "what-if" version of the hero first seen in Street Fighter Alpha 2, and Oni Akuma, who resembles the "Shin Akuma" variant of the already-evil fighter. Check out the trailer after the break.

Images that seem to depict these two characters appear in the same leaked Xbox 360 Achievement image that showed Yun and Yang. So it would appear that all four of these characters are headed to the console game as well -- either that Achievement image is accurate, or a really clever (and prescient) fake.
