Super Smash Bros 4 had to be produced by "Project Sora" ( the same of "Kid Icarus : Uprising" ) , but on 30 June 2012 it closed.
He's also confimred that some people from "Namco Bandai" will work with him, but said no characters from Namco Bandai will be put in.
On 7 August 2012 Masahiro Sakurai said : “ The game system itself is complete, so we don’t want to make it 3D or introduce complicated controls just for the sake of it. However, I am thinking of ways we can introduce a slightly different, fun experience all the while keeping the usual frantic game play. ” “ I think Snake and Sonic joining were fantastic. It made many fans happy, and it broadened the Smash Bros arena. However, introducing more non-Nintendo characters willy-nilly will lose the focus of the game, so I also recognise the n
eed to narrow it down.”
The first images of SSB4 will be shown at the 2013 E3 EXPO after a recent nintendo direct video from Satoru Iwata which can be found on Youtube.
New characters are Villager from Animal Crossing, Mega Man, Wii Fit Trainer, Rosalina and Luma, and Little Mac.

The items were Mr Saturn, Sandbag, and one Heart Container.
It could be a confirmation for these characters.
