Trying to figure out just what customers want in a gaming console is difficult and sometimes it's difficult to figure out which games would be best to download for Wii when there are so many choices out there. But not every game is a success and not every console system sells well and it's likely that the consoles of the future, including the upcoming Wii U device will need to serve a variety of roles in order to survive in a very crowded electronics market. Devices will likely need to do everything from play Bluray discs to play games to serve as an internet device.
