If Brink turns into a Halo bunny-hop fest then I'll pass and wait for Battlefield 3 instead. Parkour is not about bunny-hopping in the least so if you can do it in Brink, count me out.
Haha I doubt it will... that was just a tactic for CQC used in MAG. Though there was a delay and you could only jump every couple seconds, throwing a jump in at random moments in a firefight makes you a little harder to hit.
