Just got home with my X, only 10 min wait at best buy although reading reports from other places there is definitely some stock shortage at some places with some pre orders not being filled at amazon, gamestop, and best buy. Stopped by the Microsoft store earlier and got some free swag (pins, t-shirts) and great food, box is definitely small but heavy as fuck. setup in under 5 mins, settings restored from USB drive, 758mb system update downloading now and then we'll see if I can play AC Origins or not.
System looks gorgeous, menus run a little better/faster than S. Really, really clean migration from S to X, took like 10 mins total and copied allll my settings cleanly, much easier than when I've moved around on PS4. Loving it so far but tired, gonna play games tomorrow.
