Wii Sports Resort was delayed.

Please explain your future vision. I believe that Nintendo's efforts have made games sell well outside of the year-end holiday season. I am wondering if you think this holiday season will be tougher than usual as many of your and third-parties' principal products' launches seem to be concentrated there. Like Wii Sports Resort had been postponed for some months, is there now an increased possibility of re-scheduling launch dates?

"As you mentioned, we were developing Wii Sports Resort and originally intended to release it earlier. We wanted to release it with enough supply of Wii MotionPlus, and were confident that it would become much better with a little more time and effort."

"So we find that the reason of downturn in Wii sales can be attributed to two main factors – we could not launch Wii Sports Resort earlier and could not make the software launched in the last holiday season have longer tails."

Kirby Wii was obviously postponed indefinitely, don't tell me that a game announced in 2005 that's releasing in 2011 wasn't delayed.

As for Wii VS, take a look at this:

  Mr. Miyamoto, what can be enjoyed with the Wii Vitality Sensor, which Nintendo announced at E3? Please give me at least a hint. I think you are developing a new The Legend of Zelda for Wii. Please provide some clues about the development process and some of the new things you are trying out.

     Miyamoto:    I was hoping you'd ask about the most recent Zelda for DS. On December 23rd in Japan we are going to release The Legend of Zelda: Spirit Tracks, a sequel of Phantom Hourglass. It's really fun and challenging. On the other hand it might be a bit difficult for many new Japanese Zelda players who experienced their first adventure on Phantom Hourglass. I believe Spirit Tracks have achieved a unique style and I think you can anticipate the core value of Zelda!    And the new Zelda for Wii is beyond that. On developing the recent Zelda for DS, I found out that one of Zelda's core appeals is its uniqueness. Of course we are preparing gorgeous graphics for the sake of users' anticipation for a grand role-playing adventure. But what I believe is very important is the realistic, actual feeling players have experienced themselves; the feeling to have really been on an adventure, to have explored the unknown terrains, to have solved the puzzle through trial and errors, to have themselves grown through various experiences! In that sense, a personal sense of creativity is becoming important among us. We have assembled one of the most creative team for the recent Zelda for DS, and we want to be as creative as possible for upcoming Wii Zelda.    And on a more tangible note, we are utilizing Wii MotionPlus. What has been disclosed so far is that we are finding the most efficient way to utilize Wii MotionPlus to realize the realistic and actual feeling of fighting with the sword. As for targeting, we are utilizing the pointing system of Wii Remote on the previous title. This time we are planning a more convenient and comfortable pointing system.    And as for Wii Vitality Sensor, I think Iwata will explain later since he is hard at work on it. Based on my experiences, to measure something invisible and have it turn into something tangible like a number like weighing myself on Wii Fit, or to give a numeric value to something invisible in our daily life will be materials of new plays which will feel familiar to us or can improve our lifestyles. We are currently developing an efficient utilization around that factor.    That is all that I can say for today.  Iwata:    Please let me add some notes. If Wii Vitality Sensor is simply a pulsimeter, we did not need such a grandiose announcement. It is a tool to analyze various biological signals by scanning the pulse, in order to make something invisible visible. The point with that is you can figure out your current conditions. I believe many of you have figured out with "Wii Fit", by weighing yourself every day you could figure out how the weight would change according to what you had done. Personally I have figured out how dining-out exactly affects my weights. And there are still more invisible factors, which Wii Vitality Sensor can make into something visible, by putting your finger on that every day.    I have to refrain from disclosing too much to keep the surprises of announcement; but please note that Wii Vitality Sensor is not a simple pulsimeter. I have a strong feeling something fun will appear around this gadget, and am planning to put it as one of the next year's main topics.

This was from October 2009

I think that the idea has been scrapped.  After the WTF reaction that Nintendo got, they said to themselves, "We can sell a scale, but not a heart monitor.  Let's not push it."

Probably moved to their next home console. Nintendo has been marked this gen by the constant delays. I haven't seen a company with such internal development problems. Almost every big game got delayed for them and that ended up hurting sales pretty badly. Hopefully this will get fixed by next gen, so no last minute changes have to be made to every single game that's about to come out.
