The annoying thing about that trailer is that there is almost not a single second of it that isn't post-processed and obscured.
I would trade the whole thing in for a 10 second video of the character walking real-time through the environment.
I would have to say that I'm not a big fan of scanned environments or photorealism in games. I think scanning is a valuable tool for asset creation, but I don't find scanned environments interesting at all. They come across in a very static, sterile kind of way. I have no problem with games looking and feeling like games...not 3D photographs.
