I'll go with 170k per week once JP is counted as well. During the launch, of JP however, it could go as high as 200k I guess. Once the sales go to normal levels it will go to about 170-175k per week WW until something significant releases elsewhere.
How I came up with that prediction.....
All I did was look as the chart, and saw that the amount gaps for the PS3 and PS4 is only about a 200-250% increase over the predecessor. So I simply added that same 200-250% increase to the JP sales (which at this time/week is only at 10k or so) and that should add another 30-35k to the WW sales of the PS4.
