Of course Wii also has this kind of titles, let me just name Lost Winds. And yes, I know about Sixaxis but it's grip is quite unfriendly for playing Golf, Tennis or Baseball or for swordplay but it has been an innovation nonetheless and this and this is surely a plus for Sony.
Sony being the biggest player again in 2-5 years? Maybe yes, Sony is a big name in gaming industry, but Nintendo is surely (and hopefully) using Wii's moneyflow to project and launch an evolution of the Wii, maybe with improved controllers and better technical specs to please even those who like gorgeous graphix.
