Gamespot's just put live the first developer's diary for the PlayStation Motion Controller.
Get it after the break.
The video shows Richard Marks and Anton Mikhailov of SCEA playing about with a couple of prototype demos, as well as stuff seen last year at E3.
We're still waiting on Sony to possibly release details on the controller, such as its name, price and date. As soon as we get any information, we'll let you know.
SCEA exec Patrick Seybold told VG247's Stephany Nunneley last week the controller will be "promoted" with an "aggressive approach".
The hardware - codenamed Arc thus far - is set to release for fall.
