Soundwave, you are assuming that power is what decides the fate of a console.
Wii U isn`t doing bad because it`s less powerful than a PS4 or Xbox 720. It`s doing bad because Nintendo failed to show how different it is from Wii; provide enough original/exclusive games from launch until now (that means no droughts and as little ports as possible).
Of all Wii U`s problems, power isn`t one of them.
Relasing the tablet on the side would be a very bad idea - like it always is. Developers wouldn`t have a real idea on who would own it and for what purpose. Given that it´s there from the start, they can actually spend time and resources in taking advantage of the tablet because they know every single Wii U owner, owns one.
