Renown industry leaker Emily Rogers has made some comments on an upcoming Smash Bros. for Nintendo Switch.
In a Resetera thread, Rogers commented though that she can’t say for sure whether the Smash Bros. for Switch will be branded as a port or sequel, she can safely say that the game will be released later this year and will contain new content on top of some touched up assets from the Wii U/3DS edition.
“Unfortunately, I don’t have enough information to speculate whether Smash Bros will be branded/marketed as a “deluxe definitive edition port”, a “half–sequel” or a “full sequel”.
I can only confirm two things:
1. A Smash Bros title will be announced and released for Switch later this year.
2. They added brand new content and re-worked some of the existing Wii U/3DS content.”
