...see, this, I'm fine with. Characters logically interacting with the environment.[video=youtube;-_h7x35o3Rs]http://www.youtube.com/watch?v=-_h7x35o3Rs[/video]
What I don't want to see is Parkour: 2077. That is, I don't want to see game design or level design built around the idea of, "Can I parkour off of this?"
I'm not particularly invested in a Cyberpunk-flavored parkour game. If I wanted to play a parkour game, Mirror's Edge fills that specific role nicely.
Again, I don't mind it's inclusion, as long as game design / level design isn't built around it.
