Yes, it can.
Nintendo is using different ways for people to experience games rather than what Microsoft and Sony are doing. Instead of just enhancing the graphics, the controller and the Wii console have a connection, so the way the controller moves, it affects your in-game play.
Red Steel will be probably the most anticipated game. It showed in one of the promotional commercials online, of someone swinging their controller, and displaying on the screen the protagonist blocking a swing from a sword. After everyone laughed at Nintendo, and said that the Wii is the downfall, they will now remember how the Wii was the most played, and anticipated console of E3.
It is changing how everyone thinks about gaming. Hopefully people won't be so hard to judge Nintendo as a children company, and realize they are revolutionizing a new generation of gaming.
