Coming from a 4Gamer interview with Producer Takashi Iizuka...

You can see from our design of the DLC introduction page on our official site, we decided from the beginning that we would do three pieces of DLC. We are continuing to make it free, which is a bit difficult for SEGA, since both Yoshi’s Island Zone and The Legend of Zelda Zone were both in collaboration with Nintendo, but SEGA doesn’t have any kind of tradeout from there (note: means this next DLC is not being funded by another source).
