Looking back on the demasked hoopla, and everything Paulson said they were going to do, doesn't it sound a lot like the MySpace aspect of community that Nintendo has mentioned on more than one occasion? Perhaps the big secret is that the community will be a template of Myspace, where you can have your own page, add friends, see if friends are online, post high scores, start leagues, mailing lists and anything else you could ever want. The big thing that Demasked stressed was that Xbox live was still too impersonal. They spoke a lot about playing against faceless people, and wanting to get people to play together again. This could be what the online secret is, if we are to believe that the last secret has to do with the wifi service. Of course, it was supposed to be for the DS, but not a lot was heard about Demasked after warp pipe were debunked. Perhaps the whole idea was moved to the Wii? I personally think it would be huge.
I know the myspace aspect has been touched on briefly in a thread I can't find, but I wanted to expand the discussion about it here.
