Nintendo - Trying Not To Let Down, But Perk Up!

Last night I got an email from Nintendo telling me there is a new Wii Channel for a surprise update! The "everybody votes" channel has been launched!
All the covering up, and mystery going on with the new wii features and games seems to lie around one very basic idea. No let downs. I think channels and other updates will pop up whenever they want to keep people interested, without disappointing them if they announced a channel that is canceled or gets pushed back.
Also, living up to promises in the gaming industry is hard. With Zelda - Twilight Princess they learned a valuable lesson - Announcing games and their releases too early leads to downfall and disappointed fans. I mean they let many people down, delivering it a year late. So thats why not too much Super Smash or Mario Galaxy info is being let out. Imagine if they announced that those games would be out at launch, what would fans think now?
Nintendo's strategy makes sense in many ways. Even though you want to know as much as you can becuase you are excited, you have to realize that knowing too much about games before they are even anywhere near being released gives you a very different perception of the game. If they were to release info about Rayman - Raving Rabbids too early, they might say that it is just like the old Rayman games. And 6 months later when you get this game in your hands and it is just mini-games, what would your reaction be?

In short, Nintendo doesn't want to disappoint, they want the customer to be happy!
