The post set-off speculation that the images are of the yet-to-be-revealed nunchuck-like attachment for the forthcoming PS3 motion controller; though, the lack of an analog stick makes it difficult to support this notion. At the 2009 Tokyo Game Show, the left analog stick of a current DualShock 3 controller was used to direct characters in Resident Evil 5: Alternative Edition which features motion control integration.
A nunchuck without an analog stick wouldn’t satisfy the actual mechanic that’s missing from the standalone motion controller. It’s also possible that the new controller is, in fact, a nunchuck device that isn’t attempting to replicate the functionality of the Wii nunchuck mechanics and is actually designed for an entirely new application - maybe Sony’s working on an a secret nunchaku simulation game?
What else is Sony hiding in there?
Sony’s Motion Controller is slated for release in the Spring of 2009.
