Gamers hoping for an online component, however, are in for bad news, because one isn't planned. Activision would not say why, but IGN has separately learned from multiple development sources that Nintendo will not release Wii Wi-Fi Connection libraries to third parties until early 2007, which means that no third party launch title will have an online mode.

This is very bad, but it is supossed to be there some few games with online (RS, SSB)?
