The motion controller formerly known as Sphere is now the PlayStation Move, and Sony has come out swinging (literally) with loads of new information about the device. It still looks like a Wiimote with a little ball on top (and there's even a nunchuk-style attachment Sony's calling the "sub controller"), though Sony's works in tandem with its PlayStation Eye camera — which has been out for a while now. You can buy the controllers individually if you already own an Eye when the devices land this holiday season, or buy a controller, Eye and a motion-controlled game for somewhere under $100, which is pretty reasonable.
Some of Sony's existing games will be drafted to work with the new system, including titles such as LittleBigPlanet and the SOCOM series. There will also be all-new titles, though if you own a Wii, you're probably already familiar with them: sports games, rail-shooters and the like.
Check out the video below to see what kind of gameplay you can expect — everything from light gun shooter clones to the obligatory sports titles.
