Sony has announced that its new PS3 Motion Controller will be available in autumn this year, alongside an "extensive" line up of compatible games.
The controller will work in sync with the PlayStation Eye camera to detect movements of your hand and mimic this accurately within the game.
Delayed from its original release date of this spring, the motion controller will now go head-to-head with Microsoft's Project Natal, expected in late 2010.
Sony has promised a varied line-up of games that will work with the controller, not just from its own studios but from third party developers as well, but gave no hints as to what we can expect.
Just yesterday rumours were swirling that the controller would be called the "Arc", and despite no mention of this, Sony was clear to point out in its press release that Motion Controller was a "tentative name".
We'll be keeping you up to date with more details as we get them, but we'd expect to hear more at E3 this year where we first spied it last year. Keep it locked to Stuff.tv for the latest as we get it, but let us know below if you think Sony can battle Microsoft's forthcoming Project Natal.
