Someone over at Sony struck creative gold with this new ad which teases a possible new Street Fighter title. Their "Hadouken Cabs" commercial and website shows a guy dressed simalarly to Ryu selling transporation services. The accomanying website features a "talk to an operator" button that links to a spoof phone call where Ryu is interrupted by Zangief and a fight breaks out. 

As a total package, "Hadouken Cabs" is an awesome promotional gag that is sure to resonate with Street Fighter fans. Your move Microsoft. Check out the "Hadouken Cabs" website here.
