I think they are sorely lacking a flagship IP for older consumers. They have Mario, Pokemon, etc. which more than fills the family demographic.
Metroid, Xenoblade, Bayonetta are far too niche to give them a credible presence with older players.
And given Nintendo's poor marketing, I don't think their odds of successfully launching a new character IP on their own (ala a Destiny) is all that great either.
I'd suggest securing movie deals. Nintendo used that gambit in the 90s fairly successfully with Star Wars and James Bond so why not try it again.
The Avengers
The Fast & Furious
James Bond
Are all available open IP as far as I can tell. Spend a few bucks. Bond would be IMO the ideal get. Avengers appeals to kids and adults fairly evenly so there would be appeal there too.
They could setup a deal whereby they make the Nintendo platform + iOS + Android versions of games and maybe farm out development of other platforms (Sony/MS) to a close partner like DeNA or Tecmo-Koei or Bandai-Namco with the understanding that those versions are "different" (read: so like Bond FPS' are only for Nintendo platforms).
