User blog comment:Greninja Knight/Hidden Voice Clips discovered in Smash 3ds/@comment-25129545-20141012011317/@comment-25317463-20141012012553

all these voice clips aren't scrapped, they're just not present in the current game. Considering that a 3ds can be used as a controller for the Wii U version, it's likely that most of these clips have to do with Wii U Modes, so Yellow Team is probably present in 8 player smash.
