Xbox One: Enable AC Wireless?

ifixit found an interesting difference between the Xbox One and PS4: although they both only support 802.11n wireless at the moment, the chip in the Xbox One does support 802.11ac (plus Bluetooth 4.0 HS/LE and NFC) as well. The chip in the PS4 does not.

What's the likelihood that AC could be enabled with a software update down the road?
