Watching the trailer i think its obvious why the switch version isn't ready yet.
There are clearly two very different versions of the game on the PS4 and 3DS. The switch version would be expected to be based on the PS4 version of the engine and porting that over to the switch will no doubt require significantly more work.
It would look bad on nintendo if they have the Switch running the 3DS version.
