Travelling to 1917 to PREVENT the Zombie Event, conclusion?

[killerussian]

We're almost certain that our characters are travelling back to 1917 during World War 1.

A lot of people are thinking this map will simply be a prelude to Nazi Zombies and not an actual story continuation that'll raise more questions than answers, but from what LiamFTWinter had found from the video, his "spliced" image of the test being conducted on what is potentially the first zombie could indicate THIS is where it all began (metaphorically).

What if this is where the characters are travelling to in order to PREVENT from the Zombie events from ever happening, thereby "saving" the world and ending the story?

(judging by Treyarchs posts that every story has a beginning and an end, we can't really safely assume whether or not they were directing that statement to the story pertaining to the Original 4, or the Zombie Story as a whole. Clever)

So if the guys traveled BACK in time, would they not be the older crew, in a earlier time? Not the young crew we see in the video?

I do believe this will be about PREVENTING the outbreak though, I'm with you 100% on that.
