Black Ops II ‘Nuketown 2025’ NOT a pre-order exclusive?

So the Nuketown 2025 map for Black Ops II has been advertised for months as a ‘pre-order exclusive’ map, available only to players who pre-ordered Black Ops II. And yet today I walked into the Bx and purchased Black Ops II and still received the Nuketown 2025 map. Could it be that not enough people pre-ordered the game so they just stuck all the pre-order copies on the shelves? I don’t know. Anyway I got the ‘exclusive’ bonus days after the game was released. No money down, no pre-order, nothing. Just walked into the store and I was rewarded with the map. Win?
