According to Kotaku, Seth Killian will be starting a new gig as lead designer for Sony Santa Monica's External Development team. The former face of Street Fighter will work with Sony's affiliated studios, such as Giant Sparrow, ThatGameCompany, and Superbot, the latter of which being the team behind Playstation All-Stars. You can check out a quote from Mr. Killian below, and read the full Kotaku interview here.
The SuperBot team was created from the ground up to make this game, and they're thick with fighting game experts, including many friends I've known (or even played against competitively) for years. The overall level of combat knowledge around Santa Monica Studios was a huge draw for me—between teams like SuperBot, the God of War guys, and more, the level of fighting expertise is just insanely high, so I feel right at home.
