I know I'm late, but just for the record:
[360] 98,000
[3DS] 155,000
[PS3] 72,000
[PS4] 230,000
[WIU] 74,000
[XB1] 175,000
[PSV] 11,500
Some extra information on why I picked those numbers.
Current-gen (PS3/X360)
PS3 has the lowest number, 72,000, because I believe strong PS4 numbers (230,000) will have some impact on PS3 numbers (customers who go like "well, I'm already spending this much, might as well go for the PS4").
X360 numbers, 98,000, are strong for the time of the year. Xbox One has had some influence on these numbers, but since the price difference (between X360-XB1) is quite big, the amount of people thinking "I'm already spending this much, might as well go for XB1", will be smaller.
Next-gen (PS4/XB1)
XB1 numbers (175,000) are slightly lower than PS4 (235,000). The PlayStation brand in the USA is growing (this all started, as you might remember, when Microsoft announced the Xbox One with its DRM and Used Games policies).
Combine this momentum for PS4 with the higher price of the Xbox One and I believe that the sales ratio will be 10:13 in favour of PS4 (e.g. for every Xbox One sold, 1.3 PS4s will be sold). I can even see a 1.4 ratio happening.
That said, Xbox is still a very strong brand in the United States. Unlike some others here, I think Xbox One will have performed quite well this January.
Handheld (Vita/3DS)
3DS continues to perform very well and will have a very succesful month. PS Vita will underperform with just 11,500 units sold. The main reason the 3DS does so well is because parents and children love the 'Nintendo console'. Indeed, it is not the hardcore gamer but it are the casuals who are making the 3DS succesful. And yep, I'm saying parents have had a huge influence on the 3DS being so succesful.
PS Vita, in the future, will not be able to do much better as it does not have the proper mindshare amongst parents and children. PS Vita can be 'saved', however, by PS4 owners (e.g. what Sony is trying to do now: perfect companion device, Remote Play, etc.). Also, PlayStation Now might have a positive influence on Vita sales in the future.
Wii U (that thing on which we cannot decide whether it is current- or next-gen)
Wii U sales will come in at 74,000. I realize that this is on the high-end of what many people here expect, but I think Wii U will have some momentum from the holiday season (e.g. the drop in sales, compared to December, won't be as big as many expect).
Nintendo will continue to face problems with the Wii U with the main problem being that many people simply do not know that this is the successor to the Wii.
