no.
Wii U without gamepad would be a direct competitor to two more powerful consoles and have nothing unique to bring to the table.
The only way we'll see this happen is if Nintendo abandons Wii U and brings out a new console that is within the power levels of its competitors and tosses in just the pro and wiimote controllers.
Personally, that would be stupid IMO. I think the gamepad is awesome and the Wii U is fantastic as is. All its ever needed is games and now they are here and on the horizon.
