Will there be a new speedrun page or will this be the same for te switch port

We don't know yet

It's A Safe Guess To Say That The Port Will Have Some Differences, Due To The Port From A 2 Screen Console To A 1 Screen One. Plus, It Probably Will Have Some Changes Whether Major Or Minor, Akin To Super Mario 3D World + Bowser's Fury.

Not To Mention The Fact That Luigi's Model Is Different (I Believe), Which In It's Own Could Change The Possible Glitches And Be Worthy Of A New Page.

sounds good

it would make sense to add another console to the categories if there is a main difference
