The PS2 was embraced by casuals AND gamers, but it had no sales year that really "took off" like you seem to think the Wii will, and the pricetag of that is significantly lower than the Wii in any case, which is a major factor for casuals.
I think there is merit, as Wii and DS follow the same theme of reaching new markets, PS2 was never embraced by casuals to the level that you seem to believe, rather it was population growth and the failure of its competitors that fueled its sales increase over the PS1.
Price is important, but if it was as important as you seem to believe then PS2 would still be the highest selling console, no it is experiences, and Wii brings experiences that the PS2 never did.
Predictions:Sales of Wii Fit will surpass the combined sales of the Grand Theft Auto franchiseLifetime sales of Wii will surpass the combined sales of the entire Playstation family of consoles by 12/31/2015 Wii hardware sales will surpass the total hardware sales of the PS2 by 12/31/2010 Wii will have 50% marketshare or more by the end of 2008 (I was wrong!! It was a little over 48% only)Wii will surpass 45 Million in lifetime sales by the end of 2008 (I was wrong!! Nintendo Financials showed it fell slightly short of 45 million shipped by end of 2008)Wii will surpass 80 Million in lifetime sales by the end of 2009 (I was wrong!! Wii didn't even get to 70 Million)
