Wii U doesn't need to has better specs than PS4/X720 to be succes and lead.
Just need that all PS4/720 games can be easely and quite good portable to Wii U. If the final specs allow that, that's all necessary to lead the generation.
On the other hand, Wii U also doesn't need the best specs to offer to player the best gameplay sensation, and this i what is really important.
Excuse my english :P sorry
