There has been some talk about Super Smash Bros. becoming a launch title of Nintendo’s up and coming console, the Nintendo NX.
This rumor comes from Serkan Toto, CEO of Kantan Games Ltd, who mentioned that Super Smash Bros is planned to be a launch title for the new console.
Bandai Namco is currently developing several NX titles. Smash Bros is planned to be a launch title. I am not sure about the date – yet ;).

This is all speculation, so take this with a grain of salt. Also, it is not currently known if this is referring to a possible port of Super Smash Bros. for WiiU or a new Smash Bros altogether.
