The main question then might be, what is 'core' and 'casual'. One important thing is, that you can play Mario Kart and Call of Duty pretty casual and both can be a total core experience, espacially online. Then there's Assassin's Creed. Played it to Black Flag, but the first civilisation and assassins parts started do bore me, without those pirates and ships i probably would never have bought it and think i wont buy anymore AC's.
Assassins Creed is actually pretty much casual.
I would not define casual by genre. So if someone says that's kidfriendly so casual, he might see Wii U as a casual console. That's not my point of view.
As for games, Nintendo might need along with games they already have, i'd like to see them make stuff like F-Zero, Wave Race and Metroid Prime again and i'd also like them to do more new things, even games for a more mature audience. But that shouldn't be a copy of GT/Forza or Gears/the Order.
No one needs a third company that is doing the same.
