Nintendo should have bought THQ when it had the chance. Other than that I dunno maybe the guys from WayForward and other indie devs.
+ Of course the ones you mentioned.
About the THQ thing
Just imagine you play Saints (B)ros. the Fourth and then you go to the LETS PRETEND clothing store (the store that has like mascot, carnival, halloween costumes etc).
There you will find Samus, Link, Mario, Donkey Kong etc costumes and all those hilarious weapons like Fireflower DK-Barrels Master Sword etc. or special moves like FALCON PUNCH!
Drive and fly around with Mario Kart's, F-Zero racers, Airwing whatever. This would have been a great chance for Nintendo to get 1 mature IP plus add a ton of Nintendo to make it have mass appeal.
To bad it didnt happen.
Oh man Im actually sad now....
