Well old model;
is quite a lot more impressive graphically than new one;
It bugs me too that they used scene from E3 2014 era build and not latest one that we are going to get. Or did they swap it again behind scenes?
EatChildren had a post comparing the original scene with how the scene looks now. It's definitely a downgrade, but it's not an exact comparison since they changed the design, the location, as well as a lot of other factors.

(top is new, bottom two are old)
Downgrades don't bother me. I get it. They want to make this game work and they overshot what they could do, or things changed, etc. Who knows, I can't say. Game still looks outrageously lovely. That said, they need to stop showing older stuff in newer trailers.
