Been following the discussion at NeoGaf and those idiots actually believed the claim that the first, almost CG-like teaser was real gameplay and that the game would run at 1080p and 60fps.
I find it hilarious how people don't believe it.
Either some people still think it is "last gen" and graphic shouldn't improve that much as their PCs struggle to play good looking but not amazing Lords of the Fallen or they simply don't have a fucking clue what is going on in graphic business and their calendar stopped at 2007 and Crysis. Then there is share ignorance of developing a game and how that goes (especially for graphic)
First of all first trailer/teaser showed Drake @ night which hides ton of important detail which is visible at day and may make game look worse (as problems are visible at strong light conditions). Then there is lighting which was completely different (moon vs sun). Foliage is also completely different as first trailer showed more of traditional jungle where later showed entirely different level with foliage being completely different (but not worse in therms of quality).
Secondly there is a lot of stuff under the hood that is trully amazing for graphical nerds. For example all hair on his body are actual hair including chest hair, hands and so on and all of them behave according to physic model. Clothes are full soft bodies also behaving according to physic model. His model is truly top tier stuff if not the best model currently with insane detail. Smoke stuff coming from bullets and such is top tier stuff probably closest currently to RL.
Third it was 1080p @ absolutely rock solid 30fPS which means real framerate is way above 30fps which means at this point almost a year before release they have rock solid frame-rate where if you know stuff is trully spectacular stuff as most of games that take 2 years to develop, year before release on console usually have FPS in single diggits. If their target is 60FPS then they are in their way to make it rock solid, not just 60 with drops.
Fourth. A year time is a lot of time to make game even better looking which undoubtedly will happen.

What i don't get though is why people claim something like this is impossible where there is already game close to be relased that look even better that that UC4 teaser: The Order 1886.
We may joke about how game is shitty third person cover shooter but undoubtedly this game will be yardstick when it will be released from graphic standpoint. Not only it is game that looks as CGI cutscenes thanks to its IQ (native resolution + 4xMSAA + their custom AA solution) but it is all around impresive on technical level. First of games doesn't have cutscenes. All game is rendered same way and game doesn't switch into "cutscene mode" and gameplay mode. Every model you see is exactly the same for cutscene and gameplay down to every detail. All object in game are created with soft bodies which means they will behave realistically to different scenarios (in some boundries naturally).
And there is naturally Quantic Dream tech demo which showed what they have in store for their next game. If you don't know their work they always provided better graphic that their tech demos:
