According to VGChartz, the rest of the world only accounts for about 35% of XBox 360 console sales. Also Europeans and the Japanese often prefer other kinds of games.
Madden surely won't be a big hit in Europe and Japan.
Almost certain future PS3 million sellers I think are Final Fantasy XIII, Killzone 2, Metal Gear Solid 4 and Gran Turismo 5.
Maybe Singstar, Ratchet and Clank Future, Uncharted, LittleBigPlanet, Fifa Soccer, UT3, Haze, Heavenly Sword and Warhawk.
The problem with many early PS3 games was they were often already released for other platforms. To develop a PS3 game from ground up may take up to two years and mature PS3 dev kits weren't available until only a few months before launch. That's why many of the games only tap about 25% or less of the platform's performance.
