#SmashBrosUltimate - Smash Bros for Switch.

[Kriven]

Every version of Smash started off as a dump of the previous version.

None have been as similar as now, is the point. Certain elements were reused between games, sure, but good portions of each game were rebuilt from the ground up. That's pretty clearly not the case here. For Smash Wii U Sakurai's team built 50+ characters and models essentially from nothing. Here they're starting with models and coding for 50+ characters right off the bat. It's not a comparable workload.
