True, John.
But PS3 was able to jump nearly 20% in Japan, year to year, and nowhere close to that in America. Wii's increases in both Japan and America were nearly the same.
Still, there is a lot of 'settling' going on in the numbers. Like you say, February / March will be of interest as the holiday fluctuations settle out, though moreso for the Wii. PS3 with its Europe+ launch in March, will need until May before we get a good picture of how it will be, year to year overall.
Torturing the numbers. Hear them scream.
