After having watched the portal mode announcement trailer, I'm very impressed and excited now!
Though unfortunately there still wasn't a whole lot of gunplay footage in the trailer, but from what they have shown, it looked different than the first trailer to me.
if I have to be honest I wasn't too impressed with the visual recoil, the Thompson iron sights (front sight) seemed way too stable and lacking punch.
Same with the AR, the recoil of the individual shots weren't really visible in the reflex sights.
Well, maybe these clips were just too short too exactly see how it works..
I'm also pretty sure they're still working on the whole system, as it already seems different than the first trailer. I just hope they will do it right when they drop the first playable version public. Time will tell I guess!
