I love you all to death (Just so I can smash bros with you) (SSBWiiU/3DS)

There will definitely be more colors. The given colors in the demo don't even include a red color for the Wii Fit Trainer (only blue and green) which is critical for Team battles. So yeah, there definitely will be more colors available in the final product, no question about it.
