you are missing the point , if i have a ds lite or dsi and i have a flashcard , and now i want to buy a 3ds ,then if i wanted to sell my dslite or dsi ,and still have use of my flashcard,that means the 3ds would have to support flashcards, so if someone only wanted a 3ds and wanted to use their flashcard and it works on 3ds then they can and will sell the ds lite or dsi which are not being sold anymore new,that means it will be on the used market for cheap and instead of a person having a ds lite and a 3ds and a flashcart that wont buy any games ,the person could sell the dslite ,and still continue to use their flashcard on their 3ds ,but now the ds lite is back in the hands of someone who will purchase games most likely, unless they are planning on getting a flashcard,keeping the 3ds from playing flashcards only makes the pirates have to have 2 systems that their not buying games for ,but allowing flashcards on 3ds means a pirate would have the option to sell the old system which means more units out there and more potential software sales
