The site is trademarked to Frito-Lay, so I doubt it has anything to do with Wii. It does however list a bunch of clues and references to pyramids and triangles, so I suspect it has something to do with a viral marketing campaign for Doritos. If you fiddle around with it for a while (drag the spinning pyramids to hit different parts of the wall) you can put your email address in the base of the pyramid, and you receive a message that says "You will be told." Some sort of mailing list. If you're really curious, put it in and whenever it goes anywhere, you'll find out.
