Will Microsoft release a first-party motion controller for Xbox 360? The company isn't talking.

"Microsoft does not comment on rumors or speculation. And I have nothing further to share," a Microsoft official told Next-Gen on Friday, when asked if the company would be releasing a motion controller add-on.

Rumors of a 360 motion controller surfaced on Wednesday, after XboxFamily.com reported that Microsoft would release a Wii-like peripheral this fall with the help of Gyration, the same company that first worked on prototype designs of the Wii Remote for Nintendo.

Microsoft is currently the only console maker not supporting some form of motion controls.

In May of 2006, Microsoft founder Bill Gates told MTV News that motion controls are "not mainstream for most games," before adding, "there's a lot to be learned about these controllers."
