The pricy WiiPads ($173 in Japan) won’t be sold separately when the Wii U launches in November.
“Through the launch window, there are no games that leverage a second controller,” Nintendo of America CEO Reggie Fils-Aime said. “And so, during the launch window here in NOA territories, we will not be selling at retail a second gamepad. But certainly, when the games come out, we’ll be making that accessory available.”
If one would happen to get damaged or broken, the only choice would be to call Nintendo for a replacement until they release.
