Aside from the mileena clips, all of the footage is from March 8/9th (day of and after PSN+ demo release). I didn't get to spend half as much time as I would have liked with this game but I got hella busy with other stuff.
The mileena command-grab-combo-loop was found by CHECK4900. It's not technically a combo but a very stupid system quirk, apparently it can be escaped by doing anything other than neutral blocking (!?).
