You're looking at game announcements, but you're not looking at the types of games announced. The new Star Fox, for all intents and purposes, looks awful. It was also partially pawned off on an outside developer (Platinum Games) and it's clear Nintendo really isn't putting much of an effort behind it. The Metroid 3DS game is Metroid in name only. Samus isn't in it, it's a co-op only game, and really looks like a poor effort.
As for Animal Crossing, it has its dedicated fanbase, but there is absolutely no way to make a ride out of it.
