Ok, it's is a long way away but i thought why not have a guess. When i mean Christmas, i mean the start of November to the start of January, aka Jan 1st.

My prediction

Wii: America = 3.6 Million, Japan = 0.9 Mil, EU/Others =  3.4 Mil / About 7.9 Mil

PS3: America = 2.5 Mil, Japan = 0.40 Mil, EU = 2.5 Mil / About 5.4 Mil

360: America = 1.6 Mil, Japan = 0.11 Mil, EU = 1.8 Mil /  About 3.5 Mil

Edit: I changed my predictions

US:

Wii 3 million
360 2.5
PS3 1.6

 Bit low on PS3 & Wii dont you think?

So you think the 360 will sell more in others than in the US?

Those aren't bad.

Wii: America = 3.6 Million, Japan = 0.9 Mil, EU/Others =  3.4 Mil / About 7.9 Mil (agree)

PS3: America = 2.3 Mil, Japan = 0.40 Mil, EU = 2.3 Mil / About 5 Mil (agree, mostly)

360: America = 2.5 Mil, Japan = 0.10 Mil, EU = 1.9 Mil /  About 4.5 Mil (don't agree)

These are last year's figures

So from that I think:

Wii: 7.5m (3.3m US, 1m Jp, 3.2m EU)

PS3: 4.7m (1.75m US, 0.5m Jp, 2.45m EU)

360: 3.8m (1.6m, 0.2m Jp, 2m EU)

 Not neccessarily, but i think that alot of people who bought the orignal Xbox in America have bought a Xbox 360 as well in America, so i think when the 360 reaches about 14-17 Mil in America, it will start to saturate. I think that in others, alot of people have yet to buy a 360, about another 8-10 Mil, and chritmas would be the ideal time for them

However, i could be wrong. 

not a bad prediction, still a bit low overall

Wii: 8.3m (3.4m US, 1.5m Jp, 3.4m EU)

PS3: 5.1m (1.9m US, 0.7m Jp, 2.5m EU)

360: 3.95m (1.9m, 0.25m Jp, 1.8m EU

Wii: Nintendo has boosted manufacuring up got the holiday. OVer 8m is way more then pausible.

PS3: This is Sony's holiday. Blu-ray sales, single SKU, great games. Basically a good formula for sales.

360: Will sell evenly with the PS3 is the US but EU wont sell past the PS3. Will sell about a quarter of a million in Japan which will be shocking but interesting to see.

I dont see 0.25 Mil happening for 360 in Japan to be honest.
