The new device is planned for Thanksgiving and Christmas sales, said the people, who declined to be identified because the product road map is confidential. The software maker hasn’t decided whether to unveil the new Xbox at an industry event such as the E3 show in June, or a separate event devoted solely to the machine, one of the people said.

 

The new version will debut a year after Nintendo Co.’s brand-new Wii U, which went on sale Nov. 18 in the U.S. Sony Corp. is also readying an update to its PlayStation console.
