As Capcom had promised, Street Fighter IV was presented in playable form at Japan's AOU Show 2008 today. While only four months have passed since the announcement of Street Fighter IV's development in October, the game already looked and played quite solid. Anticipation for SFIV was high amongst visitors to the AOU. By noon, there was a 60-minute waiting line to play a single game, despite the fact that Capcom had around 16 arcade cabinets. This is on a business day as well, so GameSpot can only imagine the crowd that will be forming tomorrow when the AOU show is opened to the public.
