I haven't watched jeusx video yet (downloading now), but gamersyde video does not reveal ambient lighting problem.
It's mostly sunny with "static" shadows, looks excellent, no objection.
The Helghast downstairs don't look flat because parts of their armor/uniform are shiny and phong/specular/diffuse (whatever) shaded.
Motion blur/ghosting makes it really difficult for me to complain about fabric faking textures of ISA soldiers under shadow also
.
I did however noticed that grenade explosions (even when out of view), cast light unlike some of the scripted explosions we have seen earlier.
In motion, it is indeed possibly best looking shooter I have ever seen on any playform (even better than that PC game, since that is not necessarily a technical comparison), but I do hope and expect they will have a better solution for ambient lighting problem.
On an unrelated note, surely people will complain about the AI and they can kiss my back.
I loved how Helghast soldiers tried to melee ISA guys and one even got a melee duel with one of your buddies, lost, of course.
On another unrelated note, if Hakha doesn't show up in this game I'm gonna be really pissed.
