The Switch is more than five times as powerful than the Wii U. It should be relatively easy to run this game flat 30fps on the Switch.
Especially since this game has been in development for Wii U most of the time.

Indeed, the Switch version should really not have any performance worries for reason you just stated.
So why get hysterical over pre-release footage of Wii U version?  I'm just not seeing reason to worry here.
