"The PS3 is dominant in Japan and Korea," the report notes, "and as of June 2008, has begun to outsell the Xbox 360 in Europe. It is also steadily increasing its market share in all other regions across the globe, including in the North American market." The Xbox 360 is still ahead of the PS3 in North America. It's worth noting that the increase in sales in Europe predates the price drop and introduction of the PS3 Slim.
Research and Markets also provided a bit more information about the distribution of console sales. Though North America remains the largest market for consoles, "The high population density and rapid uptake of technology in countries such as Japan and Korea, and to a lesser extent in Singapore and Hong Kong, see a disproportionately high level of console sales compared to the rest of the world," the report reads." Console sales are also fairly high in Western Europe and are growing considerably in the emerging markets of Eastern Europe, Latin America, and other areas in Asia."
