Should the next Nintendo handheld console have the 3D element?

[DaAndy]

I would like to be the next Nintendo-Handheld almost exactly like the WiiU Gamepad. Maybe a little bit smaller.
But i doubt that they will make the next handheld again with only one screen.
The negative thing about only one screen and no 3D would be no BC for 3DS-Games, but that would be OK for me.
