Next genereation Nintendo needs to use the franchises of Mario Bros (with DK in it), Zelda, Metroid, Kid Iccarus, Mario Kart(Mario Kart meets GTA minus the gore), Mario Party(the minigames should all be 2d platforming stages), Star Fox (flying only), Fzero, and Super Paper Smash Bros; and all of those franchises need to be online multiplayer/coop games.
Other than that I want to see nothing but new original material. Nintendo needs a new original AAA shooter in its deck of cards as well as a traditional in house RPG.
