I actually hope Ultimate is the final Smash of Phase 1, if you will, and that the next Smash is a long way away and revolutionizes the genre with many new features, modes, better online, story, etc. Because of this, and to make it really feel like a phase 2 rather than just another Smash sequel, I hope that they eliminate all characters from games not available on Switch (Nintendo or third party) or the next device. I want the roster to feel next gen just as much as the features. Cut everything pre-Switch unless they are making a game for it in Switch 2, then freely release said character around launch of their new game to hype it up alongside Smash. Let Ultimate be the end of Super Smash Bros. Let the next game be the beginning of Ultra Instinct Smash Bros.
