The racer, which throws the traditional MotorStorm formula into a hazardous urban environment, was originally due out on March 17th in Japan. It's now been marked with a "TBA" release window. Like SEGA, the publisher cited "various circumstances" as the reason for the delay.
In addition to the MotorStorm delay, Sony's also temporarily closed down its PlayStation repair and information centres. The PlayStation Network's fine for the time being, but Sony did note that there may be some instances where the service will be difficult to connect to.
