After everyone who's looking for one gets one, I think it'll be atleast between 100k-200k a week for several years.

After seeing those sales numbers earlier...I think I want to change my vote. XD

I think that the ps4 will sell about 1m to 1.2m in january, the Xbox One 650k to 800k and the Wii U 350k to 450k.

100k or more. Yes, it's not out in Japan yet, but PS3 at a much higher price sold 74k/week or more in its first January, without Europe, and after 40GB model launch, at $399 in USA and 399€ in EU, it never dropped again under 100k in the successive Januaries. Well, it also depends on supplies, but if Sony managed to resupply it at 400k/week or more during Xmas period, 100k shouldn't be a problem, even having to build up stocks for Japan launch.
Anyway, until after launch Japan sales will settle, there will be a certain degree of uncertainty, WW monthly sales will be high or very high, but there could be weekly temporary shortages in any region except Japan (Sony will obviously concentrate on it in its launch window).

With WW supply 100k, without WW supply 50k.
