Ben-DutkaThis makes a whole lot of logical sense, doesn't it? We just hope the mechanics of it are sound.
It seems Sony might be planning to combine the standard Dual Shock controller with the new motion-sensing PlayStation Move technology. This "Hybrid Separable Motion Controller" has been patented after a filing in May 2011.
The images show a combination of Sony's traditional gamepad and the Move, and available information indicates features like a "magnetometer" and an "accelerometer," plus vibration support and audio playback through an embedded speaker. However, they wouldn't be able to jam it all on there; the PlayStation Eye would still be necessary for the Move aspect of this hybrid. There's also a chance that all games will be able to detect if the separable controller is split in two or not.
Right now, it could be interesting to assume this nifty new controller will debut with the next generation; i.e., maybe it'll be the default gamepad for the PS4. But at this point, we can only guess, so…
