It’s the PlayStation Arc, THQ says

During their on-going fiscal 2010 third quarter conference call today, THQ perhaps unintentionally confirmed the name of Sony’s upcoming motion controller — while talking about games for the controller and while taking questions, CEO Brian Farrell repeatedly referred to it as the “Arc” Motion Controller.

First hints towards the name came late last month when it was discovered that Sony had registered the domain name.

The controller will arrive this fall, Sony announced recently.
