A few juicy hints were dropped by Microsoft’s Robert Walker on Monday in regards to a special FPS controller in the works for the Xbox 360. His comments were made at Gamefest in Seattle, and he was quick to clarify that Microsoft has no concrete plans for the device, but that it’s more of a long term exploration. Sadly, it’s no replacement for the tried-and-true keyboard/mouse combination: Microsoft is merely working on a new right analog stick that would be better with the precise movements required for FPS and game types. The controller wouldn’t replace the current, well-praised offering, but would merely be an option for enthusiasts and competitive types. Microsoft is also dropping more hints about some sort of motion sensing technology implementation in a future 360 controller.
