DVD is definately nearing the end of its life cycle for games, but we need to be a little more realistic about what is going on here. The business model for this gen is DLC, it's that simple. It's about money and how companies can increase their revenue without doing any etxra work.
Some companies are more responsible than others when it comes to offering DLC (i.e. large amount of content that clearly is post development). Capcom is not one of these responsible companies and it's up to us reject this content and reject this game. Don't buy the DLC and don't buy the game, send them a message.
