We just got the Dual Shock 3, but it seems Sony isn't about to rest on their laurels. Yet another controller could be on the way, and it may be a nod to the Wii's remote motion-sensing functionality.
According to multiple sources (including Kotaku and BigFatCheats), Sony has prepared a "break-away" PS3 controller of sorts; it's a device that will break apart into two individual units, and apparently, working controllers have already been handed out to development partners. Nobody has any idea what it's called or when we might see it on store shelves, though, and Sony remains mute on the subject. The only details we have include a small device that actually attaches to the body; on the hands, for example, will let you move the character's hands on screen. There's still a lot of controversy over whether or not this thing actually comes together into one controller, as some believe it comes as a split-apart unit and stays that way.
Any other details are few and far between, and until Sony decides to make an announcement of some kind, we'll probably be in the dark. Of course, there is the possibility that this new PS3 controller might be unveiled at E3 next month, so we'll keep our eyes peeled for that.
