The download is going to be about a half of a gig, 542MB so it is nothing too crazy of a download.
Sony Computer Entertainment Japan got Motorstorm first late last year before the rest of the world but it shipped without any form of multiplayer. The U.S. and UK releases though included multiplayer. It seems that Sony has thankfully not neglected the Japanese gamers here as they are now getting some new content.
Sony will also put out a demo with the expansion pack which will include a course and two cars for gamers to try out if they havenâ€™t played the gem that is Motorstorm yet.
