Unconfirmed Map?

We think we have spotted an unconfirmed Black Ops Multiplayer Map, which we think is different to any of the confirmed maps we have seen so far (Cracked, Launch, Radiation, Summit).It has only been shown in (we think) the wager match trailer, which is gameplay by treyarch employees only. It seems to consist of multiple large warehouses and a track down the middle. The terrain looks abandoned, there is some sparse snow and factories that seem to be falling into disrepair. We've taken a look at the minimaps and I cant spot any overlaps between the confirmed maps minimaps and this maps minimap. What do you think? Image Below

Note the sparser snow and rusting pipeline in the back ground. Seems abandoned
