Now you are just pretending you're not reading the posts. THE WIIMOTE + NUNCHUCK COULD NOT PLAY GAMECUBE GAMES. was it clear now? If wiimote and nunchuck could be used to play gamecube games through BC, a port wouldn't be necessary and sales would be the same. Unless you think the wii u successor's controller will remove buttons from the gamepad, it won't have any problem playing Zelda U.
Wind Waker was an old game probably already out of print. You expect sales of every previous gen game to jump with a new console that has BC?
WW only came out 3 years prior to the Wii's launch, your point was a port isn't needed if BC is there yet Wii had BC and even was compatible with GC controllers, this makes your whole but but Wiimote argument null and void when trying to back your argument here. What further kills this argument is that the only input missing on the Wiimote from the GC was the C-stick which is used for the camera, the Wiimote and nun-chuck actually has an extra button in its place so yes you could easily play TP with that controller with out the MC implemented but guess what a port still happened.
Straight up TP shoots down your argument, the are various reasons why a port is done and it's more then just controls.
