Viewing it again and browsing the comments here, i think it will be a lot better than what it looks like in the video.
First of all, the smoothness factor is top notch and fluidity can make hi-res graphics appear very impressive, even if they are not technically so. Since this is WIP and we're expecting improvements, i guess it will be even better. Not to mention that high-res fluid motion on a 22" or bigger will look so much better, even if the settings used are the exact same as those used in this video.
The reason it might seem a bit underwhelming to some is that this is low-res youtube (no 720p/1080p option in the video), reflective layers and various effects might probably not be finalised, plus we don't know what was the original resolution used during gameplay, AA/AF settings, if a low-spec PC was used that forced lower detail settings and so on.
Long story short, if this was taken from a dual core or old quad with nVidia 8800 or comparable Ati generation cards i will be very impressed, as it would indicate an ability to scale perfectly and it's not shabby at all. Roll on the next updates with high-res youtube videos running on high end PCs, then we will be able to really decide
