If you do not consider the Wii a success then I wonder what it takes to reach that level for you. Everything I've read was that Nintendo made money on each Wii sold since day one. According to Wikipedia the Wii has outsold both the Xbox 360 and the PS3 by a significant margin. I would also say that most likely Nintendo has never made that much money from third-party games (I'm sure there are exceptions), for them the money is in their first-party games on their hardware. Regardless of your personal feelings towards the console itself, saying it isn't a success seems just wrong.
