What we know so far from the interview with Yoshinori Ono, SFIV's producer:
- Set after Street Fighter II Turbo and before Street Fighter III.
- The main focus at the moment is developing the 12 original characters from SFII.
- New revenge meter builds up when you block.
- New female characters?
- Worldwide ranking or organized online tournaments?
- Chun Li's thigh's unknown.
Here are 5 videos including the Hadouken and the Dragon Punch.
