Wii will drop the most in raw numbers. I think many will be suprised how far it can and will fall in Japan, expecialy.
Everyone forgets that the Wii wasn't supply constrained in Japan. Everyone that wanted one, for the most part, got one. Suppliers had been stocking up for months.
Because of the supply being so readily, I see the Wii dropping to 50-60k/wk by mid or late January, and beginning to hover a little bit lower than it did last year, at a similar timeframe.
As for percentage, I think the PS3 overall will drop the most....Expecially in Europe, where it had the biggest increase. The price drop had a great effect for the holidays because it was so close, and people wanted PS3s - now the luxury supply of money will be gone, people just won't have the cash to invest in a $400+ system that won't see many more exclusives come it's way (or meaningful games) for awhile.
X360 will be somewhere in the middle - it'll have a big dropoff in Europe and the US, but won't see the percentages the PS3 had, since the price drop was somewhat more "well rounded" and should help the X360 year over year.
Back from the dead, I'm afraid.
