What to expect for January in Wii/PS3/360 sales

[NJ5]

Let's compare the first two weeks of December 2007 to January 2008 in order to form a baseline expectation for January 2009:

VGChartz Hardware data for the period 08th Dec 2007 to 15th Dec 2007:

 

Console	Wii	PS3	X360
Total	1,396,995	990,164	941,934

VGChartz Hardware data for the period 05th Jan 2008 to 02nd Feb 2008:

 

Console	Wii	PS3	X360
Total	1,570,736	1,074,347	725,353

 

As you can see, January sales are not that different from the first two weeks of December. Here are the first two weeks of December 2008, which should provide a rough idea of January 2009 sales:

VGChartz Hardware data for the period 06th Dec 2008 to 13th Dec 2008:

Console	Wii	PS3	X360
Total	2,737,371	763,278	1,382,537

 

Wii supply will probably not be big enough to get these sales. As for PS3 and 360, I don't know what to say. It would be interesting if the gap was that big in January

Do you think these are reasonable predictions of January sales?
