Lack of Zelda = Dissapointed people.
Lack of Pikmin = Dissapointed people.
4 Mario games = Way too much Mario, no matter how good the games may be.
Also, Wii Vitality Sensor is just another thing for people to pick at.
Well, Nintendo has a new Zelda... on the DS. If Sony pushing everything on the PSP this year counts for something, along with two Mario games there, then Zelda on the DS counts for something. In regards to the Mario games, I guess Nintendo wants to see if too much Mario is better than not enough.
I count the Wii Vitality Sensor as something like Natal. You need to see the price point, plus software support, before you pass judgement. They may actually come out with cool stuff that is like a lie detector or another self-improvement game where you win by getting your stress level down. Again, it is all speculation as of this point.
