The Wii is one of my least favorite Nintendo consoles, and in no doubt, makes me feel that Nintendo's net console will be disappointing in some way, compared to Sony's and Microsoft's offerings on their consoles (including third party support).
It seems that most of the third party game companies that matter to the long-time gamer did not want anything to do with Nintendo 64, Gamecube, or the Wii.
It's easy to see that Nintendo's next home console will suffer the same way, and I don't think I'll want another console like that again.
To combat this, Nintendo NEEDS more development studios.
