So according to Nintendo, the 3Ds Slide Pad Expansion will cost ¥1500 or 14,20€. It will be optional and all games supporting it will have a separate mark. It also needs a single AAA battery to work. Oh yeah, they’ll provide that one battery with it, but they could’ve added a bonus battery that would’ve given the system more battery life.
Also, the new Mario game for the 3DS seems to rely in “surprising” the player by making stuff coming at the screen. It will have no impact when most of the 3DS players are turning the 3D effects off after fifteen minutes of playing.
Nintendo also seems to try get more “girl gamers” to the 3DS with “girl games.” You don’t get female audience by making dress-up games, you get female audience by making well balanced and well crafted games. Make a proper 2D Mario and female audience will flock 3DS.
