Don't listen to these folks, Grey Acumen. A complicated question deserves a complicated response. The idea that every topic can be solved with a couple of pithy one-liners is one of the biggest fallacies of our current generation. I read your entire post and enjoyed the discussion. Anyone who goes out of their way to declare "I refuse to read anything that long!" is only proclaiming their own ignorance.
The suggestion I would make is to perhaps try your hand at some more specific predictions; the only one I saw in there was that the Wii would be ahead of the 360 in worldwide sales by September. It's one thing to say the Wii will win, another to try and predict where sales will be at the end of 2007. Anyway, something to think about. 
Also a minor mistake: the 360 sells for $400, not $500.
End of 2008 totals: Wii 42m, 360 24m, PS3 18.5m (made Jan. 4, 2008)
