Man, Activision is really pushing its new Elite subscription service. Not that we blame them -- it's a smart idea. Now Activision has completely 'mapped' out its DLC schedule for 2012, and it looks as though they will be regularly releasing new maps and missions exclusively for Elite subscribers.
You can find the entire schedule at Call of Duty's official site, but it looks as though Activision is planning to release new downloadable content for the game every single month.
The Piazza and Liberation multiplayer maps will be available today.
