Personally, I expect that Nintendo went for such a wild departure from conventional thought with the Wii because they realized that if they stuck with the tried and true formula this would be their last console ...
I could be completely wrong but I believe the DS was released as a third platform because Nintendo did not want to give Sony a 18 month lead like they had with the N64 and Gamecube; when Nintendo started to see that they could compete with Sony by releasing at a similar time and being different the Wii started to become a fleshed out console (rather than an add on).
