So recently, I have been re-reading the comics and have been giving some thought to the direction this story may go given that issue #6 is the newest piece of media in this canon. I have been thinking of Blundell's tendency of teasing future maps with Black Ops III. There were little notes and coordinates connecting the current map to the upcoming one. But one small easter egg was found but shortly forgotten in Der Eisendrache that has only re-appeared once: at the last page of Comic #6. The easter egg in question is the London newspaper easter egg, which as of right now is not very well documented. There is a newspaper in the control room of Der Eisendrache which details a huge parade, pictured here:
Upon acquiring the flaming plunger through another small easter egg and killing zombies near the paper with the plunger, the zombies will warp away as if being teleported, and then upon looking at the paper it looks like this:
And after getting even more plunger kills, the paper will change once more. I appear to have run out of space for posting pictures, so I will post the others I mention in the comments. The last iteration of the paper reads "'ZOMBIE' ATTACK IN THE HEART OF LONDON!", with a nearby panel reading "Parliament gathers for emergency meeting"
The running theory with this easter egg is that since the plunger is taken from another time through time travel, killing zombies with it causes them to be sent through time to London, and we are changing the future through our actions. Now, this is a neat little easter egg, but it was not solid enough evidence of things to come to really be sure. However, over a year later, issue 6 of the comic series ended with an altered loading screen from the past, very similar to the ones in previous comics, but very few talk about this one. It appears like the original Mob of the Dead loading screen, but with a page torn and Richtofen's scribblings. But more interesting is the newspaper clipping tucked behind the page, which matches exactly the final iteration of the newspaper from Der Eisendrache, with the Parliament meeting text visible.
On one hand this could just be a way of connecting the theme of changing the past in the last comic to the paper which represents such actions. But I feel it is somewhat symbolic for this to be on the final page of the entire series, marking a sort of teaser for the future. This paper appearing twice is, I think an indication of London's future appearance in our game.
Personally, along with London, I feel Mob of the Dead will be remastered, with Victis as the playable characters, similar to The Giant. My primary reasoning is that Victis is put on ice at the end of the same comic teasing London, under Alcatraz. Also Blundell stated that since Mob was not in Chronicles, they had another use for it in the future. If that is the case, then I think the London map may be a stand-alone map with actors like Shadows of Evil, if we are following the same formula as BO3. But, Treyarch is known to break the formula, so who knows how this will play out?
What do you all think? Also, thank you @anonymous for suggesting I post this.
