It seems that Nintendo has now registered another batch of trademarks related to the Wii, after the previous ones they registered last month. Here they are;

• WiiCan
• WiiClub
• WiiCommunication
• WiiDiary
• WiiHappy
• WiiHealth
• WiiHome
• WiiKids
• WiiMap
• WiiOnline
• WiiSenior
• WiiWords
• WWWii

Out of all of them the last one seems to be the most interesting to me, it could relate to the Opera browser that is coming out for the Wii.
