I wouldn't jump to too many conclusions based on these videos. It's a promotional trailer and it's supposed to look exciting. There are some visual effects that I suspect aren't in the actual game, like ground-level camera views and shaking camera from nearby explosions. It wouldn't surprise me at all, if CA (or their advertising agency) had sped up some of these scenes for visual "impact". The real test will be the first playable demo. Then we can debate combat and movement speed.
