Yes but you seem to think these UE4 shots are somehow dissappointing. The very clear implication is that you don't think there is a huge improvement. There is. Especially when we see these things in motion. Not only this but some of the things shown in the UE4 demo are things that are specifically weak in current gen games. For example the mountains in the distance they showed. Compare those to the mountains you see in the backgroudn when you arrive in tibet in UC2. There is such a vast difference.
Is there a video of this available?
Not yet. However a lot of things going on in the screenshots are harder to appreciate when not moving. The lava flowing, snow, shining particles etc. It may possibly be public in June.
For comparison I found the mountains I'm talking about. I'm not entirely happy with the UC2 screens I can find though, something seems a little off. If someone could find other versions I would be happy.
So background mountains in UC2
And those in the UE4 demo
