How many times guys u can only play with the GCC but if this was a What if u could use this controller thread then ok i stilll would play with GCC
No. Rumour is not fact. Sakurai said 'we might not want to throw away our gamecube controllers.' That is not the same as 'classic controllers won't work and you can only use gamecube controllers.' That doesn't even make sense. What about people who bought a Wii but never a gamecube? Games like Smash Bros. are what the Classic controller is for, and I bet one's even going to be packed in. Nintendo is going to want the Classic to come into wide use. Don't believe everything you hear.
Also, we don't even know that the Wiimote won't be used. Sakurai said 'at least not in normal play.' Note: hundreds of games have multiple controller configurations. Normal play could mean the default is the Classic controller but the wiimote/ thumbchuck could work, too.
Also note: this game is under development. Nearly everything is subject to change.
Mark my words, Classics will be recommended. You will be able to get them bundled. Gamecube controllers MIGHT work. And if they do, the game will still be designed with Classics in mind, and if there is 4+ players, you'll NEED classics.
