Nintendo need to buck up their ideas. Now they know that they can't forever rely on the likes of Mario, Zelda, Kirby etc. to keep themselves alive. The negative reactions to their latest projects only go to suggest that things will most definetely not remain peachy forever. And yes, I am talking about games like Zelda: Wind Waker and Mariokart: DD, because they both had problems with them. Some may dispute that MK:DD does not, but you can't argue that it is to everyone's taste (need I go on?).
Their attitude to hiring out 1.5 party support is, in my opinion, a very good thing. Allowing others to make new things out of old franchises but with the fresh perspective from another's eyes (Mario & Luigi, Metroid Prime, F-Zero GX). However, they should create their own new content along the lines of Luigi's Mansion and Pikmin, as whilst these were ultimately flawed in a big way (length), it shows a more open approach as to what can be included in it's new games.
