I think the most interesting figures this month will definitely be PS3 / 360
Wii is by all accounts entirely too supply constricted to take anything out of the figures.
In terms of supply, the PS3 is touted to have had approx 100k per week since Dec 31, we all know that retailer's warehouses are bluging with 360's
In terms of PS3, *assuming* that the 100k / week is true, then anything less than 300k can be taken as a little dissapointing, especially with the initial supply/demand situation. Of course it's entirely likely that people who couldn't get a PS3 for Xmas most likely spent their green on something else and are now waiting on a PS3 till more AAA games come out...
360 on the other hand posted solid Xmas figures, and also had a major release in Lost Planet. Also after Xmas there has been a chance for people to really compare the 360 and PS3 in stores.
Any less than last year's January of 249k for 360 is very poor IMHO:-
Great supply
Better cheap, games, more AAA titles
However, what I think is likely is that 360 is very soon going to find itself saturated at the current pricepoint and PS3 will not be far behind.
360 - 225k
PS3 - 265k
I think both consoles will suffer after Xmas, with the PS3 being cushioned by buyers that could not get it in 2006. The main issue PS3 might have is Playstation fans that are quite happy with their PS2 for now, at least until the must haves are out, and the price comes down.
Wii is a crapshoot in that we have no idea of supply.
All just IMHO.
