Wii meant we, but the hardcore gamer felt left out. That's why U meant you, the hardcore gamer. Hence why Call of Duty, Assassin's Creed, Batman and others were used as reasons to buy a Wii U.
I'm aware of that, I mean that the word super has an actual definition so adding Super to the title is self explanatory. U in itself means nothing so adding U to the end of a title adds nothing of value to the consumer.
