Copy pasting my post from the general thread, I am sorry to be the bearer of (possible) bad news. Hopefully Isaac is still in.
So for those who read my previous comments. I wanted to believe this leak very much and I was trying hard to prove it to be true. Vaanrose and I took all versions of the mural and started pinpointing "spots" that have never been visible in any version (when characters get moved around, some new spots get revealed and some new spots get obscured, but some spots are obscured in every single version) and then compared those spots in the leak to the E3. In every single case, they were different. In fact, as far as I could tell, every place where the leak differs to the E3 mural is exactly a place that has been obscured in every version.
This leads me to believe that this leak is probably fake. Vaanrose showed me how easy it is to cut a character and have photoshop fill in the blank space for you with an appropriate looking space.
My theory, that I can prove by doing it myself, is that whoever made the leak basically took all previous versions of the poster, cut all characters from each version and then combined all what he had. He then either had photoshop fill in the blank spaces left, or filled him out himself (these are all the spaces that are just wrong).
I myself found 7 different inconsistencies in this way that Vaanrose had not previously listed (so add those to the list he has already provided).
You might be able to try debunking the background, but any minor blemishes or things not matching up pales in comparison to the rest of the information we have working with here. I've seen the comparisons everyone's pointing out and I'm not colored impressed with disproving the leak.
If one static, blurry picture is all we had going for this, no one would even give this the time of day to begin with in the first place, but it's not. There's too many details that just work out too well to just be from a mastermind or coincidence. For instance, just the thing the banner is printed on. It's used for advertising materials at stations in stores. To make that, you have to get the scaling and measurements right and have access to specialized printers and knowledge of lithography. There's evidence to show that there's multiple of the same thing being printed, like you think they would for a graphic design company. One person did all of that?
You have other evidence that they're also designing a chandelier in the same manner and the original photos both show it with crystal clarity. Because you have to zoom in and pixelate everything, of course details will be muddied. Crystal positions or clouds not looking right just seems like the wrong angle to take.

posted above me, when all of these characters are moved around, they reveal completely new parts of existing ones. If someone with fantastic artistic and photoshop skills put it together... okay I think I can accept it. But, now you're adding someone who has the most ridiculous looking resume I've ever seen. What can't they do? It takes time and people to put all of this kind of stuff together, and all of this was done in a month with one person?
I haven't even mentioned the Grinch stuff or the CSI work people have done with the actual employee whose name showed up which also corroborate all of this evidence.
Occam's Razor just says otherwise here. I appreciate people trying to temper expectations and find out the root of things before it really burns us because it turns out to be fake. I would love to call it fake if that were the case. Maybe I'm mistaken here and there's something I'm not seeing. Is there a guy out there that has a hobby of mocking up graphic designs of things in his free time? Or even more ridiculous, someone who has the wherewithal to hatch a scheme to make even Professor Moriarty blush? Well, I'll prepare to have my mind blown when that day comes, which is going to be very soon.
