First shown on the official Japanese Street Fighter IV's Nakky blog a week ago, a keychain that replicates voice clips from Street Fighter II will be available in March. Bandai has also released a video showing the keychain in action, which includes the generic battle sound effects and voice clips feature we've seen in other gadgets before it. However, this one also includes an "imaginary battle" feature that allows users to fight against "imaginary opponents" and progress through the arcade mode using only the keychain. Better yet, different people who own keychains can fight against each other! Players who don't want to see their characters lose on screen should definitely look forward to these. Sadly, the previous set of Street Fighter IV keychains didn't make it to American shores, so these probably won't have much luck either. Hit the jump for the full video from Bandai.
