It appears that the Opera Product Page may have been hacked. The first paragraph of the page states:
The most full-featured Internet power tool on the market, Opera includes pop-up blocking, tabbed browsing, integrated searches, and advanced functions like Opera’s groundbreaking E-mail program, RSS Newsfeeds and IRC chat. And because Wii know that our users have different needs, you can customize the look and content of your Opera browser with a few clicks of the mouse.
The “Wii” links to a GeoCities site that is someone’s personal site. There is no way that Opera would have done that, even by accident. I guess only time will tell!
