Either Nintendo just bought a large lot of "fake estate" (as opposed to real estate, which exists in the real world) in the ultimate non-game, Second Life, or someone who really loves Nintendo is up to something. A mysterious island has appeared in-world called "Nintendo Island." It's currently closed to the public (and devoid of structures), so we can't tell what Nintendo (or whoever) is up to on the island.
If this is Nintendo's doing, they could be setting up a giant advertising initiative on the island, with videos of stuff like Brain Age and Cooking Guide. Second Life residents are probably a good audience for Nintendo to attract -- they've proven that they're willing to spend a lot of money on things that are vaguely game-like.
