No, the map assets and placeholders are there. Not functional DLC with all of the development stages polished attached. People who don't understand game development jump to that conclusion but it's fundamentally misinformed and incorrect. Not to mention many games have assets walled away from the main game that are either relics from old development plans that haven't been removed, or again, have been placed on disc to be updated on the future but not require gigabytes of patches.
