EA never really got the Wii
I worked at EA on the Harry Potter franchise a few years back. When the Wii came out, we immediately jumped on it as the controller was the perfect wand. When we told other parts of EA that Wii was our lead platform, we were just laughed at. Most people, especially in North America, just refused to accept that a console that wasn't 'the most powerful' could possibly the lead platform for a game. They only started taking notice when they saw what Nintendo and other publishers were doing with the gameplay, rather than just making games that looked nice.
