I'm not sure why NSMB Mii pretty clearly has the exact same graphics as the Wii game. Is it because they want to release a major Mario title within a year of launch and focus on new gameplay elements and maybe certain new features (aka see: LBP) instead of forcing Wii U to be considered just "Nintendo...but HD graphics ZOMG", when it is clearly not just that? Or is it just a lazy port made to turn Mario even more into a cash-cow with less effort and to make lots of money on sheep buying the exact same game like it's Megaman, except far more profitable?
These are interesting questions. The answer is "yes".
Bring on E3.
