Some of the prototypes have been tested with upgraded components you'd use to improve the performance of a PC gaming rig. It's not clear if and when Microsoft intends to launch an upgraded Xbox One, but Phil Spencer has already hinted the company will "come out with new hardware capability during a generation" that supports existing and future titles. A new wireless chip could be just a small part of the optional hardware upgrades to the Xbox One that Microsoft is planning.
