Week over week the big improvers are DS, PSP, and Wii; with PSP and Wii switching places from last week.
Are PS2's 10K hardware days finally over? It has done so a few times this year, but is now failing to do so in the peak of the holiday season and doing far worse than the year before.
GCN and PS3 get compared a lot, and now their third year numbers are looking pretty similar. This is a turnaround from earlier in the year, where PS3 got an early lead and kept it with things like the MGS4 spike. However, GCN was a bit of a holiday machine and is making up ground FAST in the last weeks of the year. Unless PS3 hits 91K next week (more than a doubling of this week's sales), it falls behind.
Famitsu Software Stuff
Animal Crossing City Folk (3281) continues its previous trend of both failing to keep up with Wild World (95) while still doing much better than previous console releases. It should soon be the #1 console version.
Inazuma Eleven fell off the charts, but has returned with legs showing.
Pokémon Platinum joins the 2 million club. It also apparently passes up Pokémon Emerald on the charts, though since Emerald's last update was 2007's Top 500 list its number is out of date.
New software group: Taiko no Tatsujin
Among known numbers, Taiko no Tatsujin Wii's (3314) first week gives it rank 9 of 15. At 115K, it's the best first week of the series since... actually, ever, it appears.
