User blog comment:AdvancedRookie/Activision hints at more frequent DLC and content variety/@comment-1985896-20120105231006

I would love to see old maps from CoD4 and MW2 in MW3, some maps were just so much better than the maps in MW3. But they shouldn't make such a map pack to expensive though, because when they put CoD4 maps into MW2, they had to upgrade them for the new engine. But now MW3 has the same engine as MW2 had, they barely have to do anything.

And I also think something as weapon DLC would never come. It's just too complicated.
