The 3DS wasn't helped much by Nintendogs, yes Nintendogs + Cats crawled its way to barely 3 million, but that's not impressive given the DS version sold 23+ million copies and triggered a pronounced rise in DS hardware sales from its release. That's a huge drop off.
3DS had a horrible launch on the back of Nintendogs + cats indicated as a mass market phenomenon its time (much like Brian Training and Guitar Hero and probably soon enough, Just Dance) was over.
