Update 2: Sumo Digital producer S0L has said the following over at The Sonic Stadium forums:
You know, when they (SEGA) pitched us the idea we went ‘The fans will go wild…’ I think they didn’t get what we meant from that though
End of the day she hasn’t replaced any SEGA characters, she’s an extra and we’re very happy with the vehicle design we’ve done for her, which incidentally isn’t the one you might think it is
UPDATE: Game Trailers just revealed that Nascar driver Danica Patrick will be in All-Stars Racing Transformed. Remember her from that one SEGA game? Wait, she’s not a SEGA character. But she is racing in a SEGA branded racer which will be revealed at SEGA’s E3 booth. Danica and her SEGA branded Nascar will, in turn, be in the game. I’ll admit, it’s really freakin’ weird, but it does feel very much like when Pepsiman appeared in AM2′s Fighting Vipers. Which is a good, if not odd, thing.
SEGA Blog has posted up some booth pics, including a massive car shaped thing right in the center of the Sonic & All-Stars Racing Transformed booth. Doesn’t appear to be Sonic’s car, I can only imagine a custom made Speed Star would cost a load. But it could very well be the Hornet. Daytona USA’s star racer joining the All-Star roster? What do you think is under there? We’ll know in one hour. There is a small chance that Segata Sanshiro can take the form of a car, and he’s silently waiting to burst out from beneath the sheet to put the Wii U in a headlock.
