Coming from Masahiro Sakurai...
On moving away from story cut-scenes...
"Unfortunately, the movie scenes we worked hard to create were uploaded onto the internet.. You can only truly wow a player the first time he sees [a cutscene]. I felt if players saw the cutscenes outside of the game, they would no longer serve as rewards for playing the game, so I've decided against having them."
- 3DS version will include a feature that "acts as a separate mode from the standard versus play."
- character customization will alter character performance, though in what way is still unclear
- currently considering customizations from the 3DS versions to be brought over to the Wii U version
