They still could've been usable on Wii/Wii U if they were USB though, no? I just hate the setup of having to plug controllers into the Wii Remote, always annoyed me with the Classic Controller. And they never did release that damn clip which was supposed to hold the Wii Remote to the back of the CC.
True. Still would've been nice to have official NES controllers for PC, without the need for adapters. Also would've made them forward compatible with NX (I assume it's going to have USB ports ) without the need for a Wii Remote.
