Ok so seeing as we're meant to take everything Laura says as stone cold facts.
The battery of the Switch is mediocre
The dock has additional hardware that improves performance (despite Nintendo claiming the contrary)
Nintendo will be revealing full hardware specs before the end of the month
There is a multi-touch screen
Nintendo will be revealing price before the end of this month
I think at this point, if that's true, that Nintendo wants to avoid the "underclock" talk.
Since it is a console first, they will share maximum clock specs I suppose, and avoid the mobile underclocked performance to keep the image that it is always the same experience. With or without dock.
