Hmm okay, this is kinda interesting.
All Wii predictions are in 44.4-45.6M for lifetime sales at end of 2008
X360 are from 25.8M to 26.2M
Ps3 are from 20.7M to 21.4M
If you take the average of this, the expected market share will be
Wii: 48.8%
X360: 28.2%
Ps3: 22.9%
For a comparison, the poll on the home page suggests somewhere around this:
Wii: 41M - 48.2%
X360: 24M - 28.2%
Ps3: 20M - 23.5%
So, despite all the bashing of that poll, those people end up with about the same result (relatively to each other), as some of the VGC "elite" predictors do.
If you look here though, http://www.vgchartz.com/predictions/results.php?game=154, the average prediction says that all the consoles will have negative sales of 20 million or more.
