You're absolutely right, chunk. Even with the Wii, the new experiences from Nintendo tapered away to be replaced by an endless stream of 2D platformers. There was clearly pent-up demand for some classic 2D platforming, but seeing another platformer on the Wii was getting to be as stale as seeing a new shooter on 360. Quality, freshness, variety builds a game library.
Nintendoland shows lots of new ideas for the gamepad, but there are no killer apps yet. After playing Pikmin in Nintendoland, Pikmin 3 may be the first. Nintendo needs to build those ideas into full-blown experiences, because the lowest common denominator games of third parties sure aren't going to do that for them.
"The worst part about these reviews is they are [subjective]--and their scores often depend on how drunk you got the media at a Street Fighter event." — Mona Hamilton, Capcom Senior VP of Marketing
