"Movement updates"

In the Salvation trailer it lists 'movement updates' and then shows a toon running side to side and back and forth...I laughed thinking it was a joke "i can move freely now, are they saying the current movement system is too rewarding?!"

Thoughts on what this means? More keyboard input functionality? Quicker response times?

It's sad, because I'm using wasd for skills. I hope "you'll have to have wasd enabled" is just an option.

Yes, you will have to turn on the WASD option.

Strafing. I believe that was mentioned in the video.
