Ultra Street Fighter 4's fifth character is 'very much related to Street Fighter'

A community member was worried that this new fighter would be in a vein similar to Cole (Street Fighter X Tekken), Mega Man or Asura. Hinds had this to say.
Thujal: Terrified the 5th character is going to be another Cole / Mega Man / Asura and not related to Street Fighter. And Dinosaur stage? In Street Fighter? Really?!?
David Hinds: It's very much related to Street Fighter, so you won't need to worry.
