For Wii, with the USA numbers from Nintendo I think you can expect 680k Americas 40k Japan 300k - 400k EMEAA (that Mario Kart bundle launched this week!). That would be 1.02m to 1.12m.
For PS3 I'd expect 350k EMEAA, 100k Japan, and 350k Americas. PS3 probably only would have done with 275k or something without GT5 this week in the Americas, and maybe 250k in EMEAA. I could see PS3 a bit higher in EMEAA too. But 800k minimum.
For X360...I'd expect 5k Japan, 240k - 300k EMEAA, and anywhere from 350k - 550k in the Americas. It really depends on how well those $50 gift cards for the $200 X360 were recieved, and whether Kinect pushed alot of hardware for the week. Something like 750k? Hard to say really
For DS...probably over 1m in the Americas alone. 50k Japan, 1020k Americas, 430k EMEAA or so. Good for a 1.5m week.
For PSP - 250,000 - 300,000 for the week.
For PS2 - 100,000 - 150,000 for the week
Just my guesses though.
