It's unsurprising Sony would devise a motion controller, after the gazillions of dollars Nintendo made with its Wii platform. However, as impressive as Sony's E3 demonstration was, many fear the motion controller may signal a paradigm shift for the company. Will hardcore gamers lose out in Sony's (and Microsoft's) newfound reach at the motion-craving casual audience? Tretton doesn't think so. Speaking to CNBC, the president of SCEA promised that the PS3 motion controller (and its games library) will be far more flexible and diverse than what one would find on Nintendo's machine. "Personally, it's very difficult for me to perceive God of War 3 being played with the Wii controller," he said. "It's a different experience that doesn't lend itself to certain types of games. [But] I think our [motion] controller can be used with every game that's on the system now - and every game we're working on."

In fact, Tretton goes so far as to say compatibility with current PS3 games is "absolutely conceivable." Without being able to go hands-on with the device, it's hard to judge. Are there sufficient buttons and sticks to make a 1:1 translation between DualShock and the motion controllers? While it's certainly possible, we can't see many gamers throwing out their DualShock controllers any time soon.
