Now, question: Should this even matter if nobody noticed in the first place? I'm sure there will be some people who now probably say they noticed this all along, or knew something was up, but come on, that's not really true now, is it? Nobody's going to believe that.
If our local 1080 paparazzi truly thought that something was up, or even worth investigating with the game's resolution, a pixel count would have been done ages ago. That didn't happen, regardless of what people may be saying currently. So, what it all boils down to is that this is just one more example of a game (if this is all accurate and no mistakes were made) in which something that was supposed to be so effortlessly spotted and identified, was missed completely by just about everybody. I distinctly remember posts of people mocking developers and posters who sometimes said that it was tough to notice the difference between certain resolutions, and that it wasn't always as easy to spot as people claimed it was.
We now have an example with Killzone that's very close to a 720p resolution for the MP, an MP that many people, even myself, were impressed with visually, and nobody seemed to notice anything amiss with the resolution despite this. That just about tells you all you really need to know.
We all thought it was blurry, but were led to believe it was native 1080p, thus we thought it must have been the AA solution. Don't talk about something you obviously know nothing about, please.
Nope, the guy is right. Everybody missed this. Since when has a developer telling people a game was 1080p stopped people from doing a pixel count anyway? I think I'm only being fair in saying that if the game was an Xbox One title, a resolution analysis would have almost certainly taken place no matter what the developer claimed, and I think everybody knows that. But the best part here is that if people thought the game's MP looked great before (lots of people did) then nothing should be different about today.
