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.
Side note: To clarify, I never said whether it was a sequel or a port. I only said they’ve been preparing an announcement for a Smash Bros title on Switch. I don’t know whether it’s a sequel or a deluxe definitive port.
