In the combat videos I saw neither of those was strictly true. The combat appeared quite normal and although you can move quickly it seems that many players were moving at normal speed during the firefights. Regarding close quarters, I saw many sightlines that were quite long so again this seems like an assumption and not a fact. I do admit that SMART will change how players run for cover but they should not be able to run and fire accurately at medium to long range targets unless they use ADS.
Of course there will be longer ranges but it seems that quite often it is close to medium range. Also, some previews mentioned this
"Rather than the Battlefield-inspired landscapes of Splash Damage's last project, Enemy Territory: Quake Wars, Brink's maps more often resemble the close-quarters claustrophobia of their first game, the critically-acclaimed Wolfenstein: Enemy Territory. With Brink, Splash Damage is taking the intensity and variety that made them famous, and doing its best to repackage it with more than a little charm."

And with quickness I meant the sprinting and SMART, which have their place in a gunfight even if you're not shooting simultaneously.
I have no say in the spread/recoil question, my first post on this topic was just to point out to BuckshotBandaid that not-much-recoil doesn't automatically mean no-skill-involved. [Edit: which is evident in other SD games]
