not really, the only other numbers oriented site I visit is box office mojo, you can check them out for a number of games. I'm tempted to suggest a Wii prediction game where the participant picks a date/week when Wii sales pass Xbox 360. But I cannot think of a way that would make it fair and not easily hacked as there are only so many dates on the calendar... I guess it would be just dependent on how fast Nintendo can make them. I suspectWii shortages will last till past May.
