From what we saw of it, it did.  And they said it was from in-game.  So dunno, ND's not really given us reason to doubt them yet.    Isn't that how ND's been revealing the Uncharted games anyway, in the past?

"Complete ambush of excluives". All three of them. Two of which have had mixed/negative comments.

They said that it was "in-engine", which is entirely different from "in-game". It's simply an in-engine cut-scene, there's no way to judge wether the actual game itself is polished from that. That was why I mentioned TLG. It wasn't because it think UC 4 will be in dev hell for a decade or so (because I do believe it'll release winter 2015), it was simply to give an example to prove that there's no way to tell if the game is polished or not from the little thing we saw.

They (Naughty Dog’s Studio Coordinator Rodney Reece and Lead FX Artist Keith Guerrette) confirmed to us that the Uncharted 4 trailer showcased during Sony’s E3 2014 press conference was a part of an actual level in game. Secondly, they also confirmed that the entire trailer was running in real time on the PlayStation 4 and it was all in-engine.

We've studied the video in a little more depth and have concluded that it's definitely running at native 1080p resolution (as opposed to being rendered at a very high resolution, then scaled down - a process known as super-sampling). Small clipping anomalies, a touch of specular aliasing on Nate's shirt as he sits up, along with some shadow aliasing on his forehead also suggest a real-time render. On the face of it, we're still looking at some pretty incredible anti-aliasing here for a real-time technique on a game running at 60fps, particularly when it comes to the perfect, artefact-free rendering of Nate's hair - but the combination of the low contrast setting, slow camera movement, motion blur and depth of field would work well generally in making aliasing much less of an issue.

Need anymore, or does that suffice?

3?! 

Bloodborne, The Order 1886, Uncharted 4, Until Dawn, Ratchet & Clank, Wild, Rime, No Man's Sky, Hellblade, Persona 5, GT7, FF7 Remake, Without Memory, Everyone's Gone to the Rapture, The Witness, & Deep Down then potentially Horizon, Media Molecule Game, SSM Game, and even unannounced games and some I left off.

What planet do you live on? 

But you just confirmed what I just said -_- It's a cutscene/trailer, rendered in real time, and in-engine. Sure it's a cutscene from the game, and the cutscene isn't pre-rendered, but it's not the actual game it self, as in it's not gameplay. You can't say that "it looks polished" when you have nothing to go by except an in-engine cutscene.

Right, except Corrine Yu who said it's an in-engine, REAL GAME level.  Stop clutching at straws, this issue's already been confirmed by Naughty Dog.  You made a poor comparison.

No More Pre-Rendered Cutscenes From Naughty Dog Starting With Uncharted 4 – Report [Update]

I'm not the one clutching at straws here... Again, it's an in-engine cutscene from the game. Does that mean that the entire game, including GAMEPLAY, is on the same level?

Do you seriously think the entire game is polished on the level of that teaser? Do you seriously think that we can judge the current state of the entire game, based on that one teaser?

If you answer yes to all of the above, why don't they release it this winter? Because in that case the game is done. If you answer yes to one and two, but not three, then you're a hypocrite. If you answer no to all, then you agree with me, and I don't understand why the hell you're arguing about this.

Yawn, it's an in-game level, confirmed by 3 employees.  Not sure why it bother's you so much, but I guess that's your problem.  Beyond that, they work on their schedule, not yours, or mine.  Either way, your comparison, again, was poor and rightfully shot down.  Gonna go finish my coffee now.
