dl'd the demo a little earlier. that video above just gave me reason to pull my kinect out of storage at give it a try. it makes the game just feel so natural and even smoother than it already was. preordered from amazon after i realized i ran the demo for an hr 1/2 straight :x can't wait, looks like 2k is back in full force this year.
EDIT: my only complaint so far, and it's a minor one, is that it looks damn near identical to 2k12. i know they used the same engine n all but i can't see any discernible difference. that said, i'm glad the focus on gameplay seems to have paid off so far
