The user who uploaded the video apparently is 1cgames, so i guess it's 1c promotional footage showcasing the contents and not some lucky guy getting it a full two days before the official release
I guess retailers in stores have got it delivered and maybe a few very close friends of theirs have managed to pull some favors and secure an early copy, but if there's a date lock on the DRM it's not going to be much use anyway. Maybe that's why they can't really flood youtube with in-game footage for us to see.
I know, i spoiled the fun here but it's just two more days, we'll manage
