Just re: the fun of updates on the XBone, I went to fire up my PS4 a couple of days early before Horizon comes out so it could get all the updates out of the way. I hadn't started it in nearly 9 months, so I figured I was looking at hours of updating to get it working again.
Downloaded one update and was fully updated and running in less than 5 minutes. Why can't the XBone do it that quickly?
