Kinda sad but I think the console business has changed these days.
Aside from a small handful of IP -- Skylanders, Minecraft, and a few established Nintendo IP (Mario, Pokemon) it seems like any console game that dares to be colorful or cartoony ends up not doing well.
It's not just a Nintendo issue either, seems like Sunset Overdrive did below expectations for MS. Tearaway, LBP Karting, Puppeteer all underperformed for Sony. Rayman Legends overall didn't do great despite being a terrific game. Sadly I don't think Splatoon will take off in this environment either. While Mario and Pokemon do well some of their other IP seems to be a tough sell these days ... Kid Icarus deserved more sales, Pikmin does too, DKC: Tropical Freeze really underperformed.
Colorful/cartoony games are doing well, but it's all on smartphone/tablet, where they dominate. Perhaps people are just getting their fill of those games there and the console is becoming reserved for big, Hollywood movie-like, shooters and action games along with sports and racing sims.
