I would have prefered Soul Calibur 2, since that was probably the high point of the franchise along with 3. It declined since 4 and 6 was only a little popular because it was better than the abysmal 5.

Misturugi looks a bit too stocky and muscular, and very different from the earlier incarnations. Taki was shown as a prototype and looks good, but she hasn't changed much since the early days.

Someone above said Yoshimitsu and he'd be great but I think he's mostly a Tekken character that became a recurring guest in Soul Calibur, so if he gets made it will likely be for the Tekken line.
