Expansions is 1 thing but tiny DLCs? Oh well, i guess its just increasing the profit margin from people daft enough to buy an FPS on the XboxExpansions usually at least have a decent amount of content in them for the money.
They don't want to do expansions, because if you've played BF2 and BF2142 you may remember that once expansions came out there was a huge segregation in the community between players who had an expansion and players who didn't. They finally learnt their lesson with this and opted against it. This DLC which may not look as much, isn't exactly about paying for the content itself, but more for paying to support the game, the maps, vehicles and weapons will all come free, so as a good gesture from the players to DICE, we can take what doesn't seem as much, just to help out funding the development and getting all the free content in the future.
