Just read that preview and I agree. I'm especially bothered by their criticism regarding clunky animations and crappy AI. Sounds a lot like ArmA I to me.
There also seemed to be problem with grass disappearing after a few hundred meters and players then lying on naked terrain, so prone players are easier to spot far away then near.
I dont get why this stuff hasnt being polished or redone, the weapon sounds as far as i have seen havent been improved, the animations it would seem if that preview is to believed the same.
One thing that always bothered me is why is there no ragdolls its annoying to see enemies go down in exactly the same way nearly every time, that and the lets stand in the middle of the road AI.
I nearly lost faith with bohemia after ArmaI and only for the stellar work of some the mod teams i would have given up on it, i really hope they produce polished product this time.
