I put an article up on this...but roughly speaking:
DS topped 8m again in the USA for the fourth year in a row - easily a record.
Wii topped 7m again in the USA for the third year in a row. Since they didn't say "over 8m", you can take the range as 2.3m - 3.3m in the USA for Dec, as 3.3m would bring the Wii total to > 8m in 2010. Last year Nintendo said "over 3m Wiis in the USA in Dec" and NPD (for the USA) said 3.81m, and we had 3.5m for the USA.
DS > PS2 in the USA by 1-2m units lifetime (47m-48m to 46m roughly), as DS needed 2.2m to reach 47m, but since it didn't reach 48m, it sold less than 3.2m. Nothing else (GBA, GB, PS1, NES) is particularly close to DS / PS2 right now, although Wii has more than enough left to get to 45m and beyond eventually. I don't see why Wii couldn't do 6m-7m in 2011 with a price cut in the USA to $150 for instance. That would put it at 41m. Cut to $130 in 2012 and they're at 45.5m. Gets to something like 48.5m in 2013, 50.5m in 2014 at $100, 51.5m in 2015, and 52m in 2016.
Wii is anywhere from 20-23 months ahead of the PS2 pace based on the stated range above in the USA.
