WiiSpeak trademark reveals possible unused alternative names?

Nintendo unveiled their microphone accessory at their E3 press conference, which we know is called WiiSpeak. However, from July 2 to July 4 Nintendo registered Wii to Wii, Wii2Wii, WiiFriend, WiiTalk and WiiSpeak separately. It seems likely that these are just names they were considering, but perhaps they will be used for things associated with the WiiSpeak device. Nintendo have not announced anything yet, so don’t get your hopes up. Source: Siliconera
