Rhythm Heaven has three entries, and it's also rumored to get a rep in SSB4, so it's not gonna die soon. Xenoblade is getting a sequel w/ Monlith Soft's X for the Wii U. Art Academy is getting a Pokémon-themed installment for the 3DS, and Miyamoto's IP will be revealed at this year's E3.
Keep in mind that Nintendo's not the only company with failed IPs. *points to Knack for the PS4 and Sony's constant struggle of create so many new IPs until one of them sticks rather than focusing on their older IPs*
