okay with this shot here, mark talks about how coming to the new generation(ps3, xbox360) for waw they had the idea to keep past war idea of story and really sum them all previous games up into what they think will be the best real war call of duty ever. If we follow the same pattern this year (what i thought he was hinting at) we may be getting a modern game this year, to sum up all the other modern day cods they had previously on old gen consoles.
say if advanced warfare was on the end(or you could even just consider ghosts as future warfare), it would be the exact same pattern with old gen games as new gen
if i was treyarch and i had a forumla like this that works.... i would not change it....
quick edit.... this is the only picture that the coffee stain is being overlapped by the image, this makes me think that its pointing to something.
also there could be a meaning to the heart and brain behind the timeline, as if the older games it was more about them using there HEART to create something new, which everyone loved, but now they have to use their BRAINS to revamp something old now, waw is old but loved by all
