I could not agree more with the OP.
Nintendo direct is probably the best way to showcase games, because it's cheaper and you are still able to put in interviews into them, as demonstrated in the Nintendo Direct Europe, during late april. To begin with they can showcase N-Direct at least once every one or two months and keep it nice and short, to explain some game mechanics, like for example Animal Crossing, which would have been a long presentation about that game if Nintendo decided to showcase that game during the 3DS software showcase.
