Motorstorm Not San Francisco, PS3 News - GamerZines : Free Digital Games Magazines

Despite what the leaked screenshots may have implied, MotorStorm Apocalypse isn't set in San Francisco. Instead, the next game in the brutal off-road racer series will be set in a "fictional city".
"At the moment it's just called 'The City'," said MotorStorm Apocalypse's Lead Designer Paul Rustchynsky.
"It's a fictional, west coast American metropolis, and obviously we got influence from lots of cities on that coast but no, it's no city in particular."
Screenshots of an old build of the game were leaked onto the internet over the weekend depicting a "MotorStorm 3: San Francisco" title. We imagine the name of the game may have been changed due to legal reasons.
