This was a strange announcement to me. There's already a full Mario Gold and Mario Tennis game for the 3DS. Now, they are jamming that together along with soccer and baseball (Strikers and Sluggers) with horse racing (Mario Kart knockoff). I question how full these experiences are going to be and how they will compare to the past iterations of these franchises. Strange. As I recall, the only thing similar is Mario Sports Mix on Wii and it wasn't received that enthusiastically either.
