It has been revealed that Bad Company 2 will indeed feature DLC, and not just any DLC, an actual in-game store, as producer Patrick Bach said,

“We have an in-game store where you get free content or you can buy new content to the game, so it’s a very integral part of the game that we will have a long post-launch campaign. I think people will be thrilled to see what’s in that already. On day one, you will get some really cool stuff.”

We’re sure people will be thrilled as long as it’s free. Sadly, though, it seems that EA is determined to apply the nickle and dime theory to every one their games.
