Origin would never be required. Nintendo doesn't really give a damn about EA and would never make Origin an exclusive to the system. I see less than 1% chance of this happening. Perhaps, Steam or Origin could end up on the Wii U but Nintendo would never force people to join a 3rd party online distributor. I am pretty sure Nintendo likes to be in control of their own eshop.
