But what Mr Miyamoto said was absolutely right. You can't tell most modern games from one another. Does telling the truth make you a sore loser?
Reggie on the other hand is just a spin doctor. Nintendo could lose a trillion dollars and he would say "We're disappointed by the results of course, but the future is looking very optimistic now with some strong holiday releases such as Animal Crossing: Amiibo Festival and Metroid Prime: Federation Force coming up."
Edit: (And what Reggie said was right, but it's not like Nintendo haven't done that in the past either)
