The Verge‘s Andrew Webster:
In order for the Wii U to truly succeed, Nintendo needs to create experiences that could only be possible with the GamePad, and that are good enough to make people want to buy the console. Speaking to the New York Times, Fils-Aime said that the GamePad “allows us to create content that shows different ways to play together but have fundamentally different experiences.” Now Nintendo needs a game that exemplifies that philosophy.
Exactly. Mark my words: the idea of selling a cheaper version of the Wii U without pack in software is a huge, huge mistake.
